Main Cooking Theme

A set of “freezer rules” designed to:

• Prevent food waste
• Enable quick meal prep

Most “recipes” are method rules for freezing ingredients (and sometimes pre-cooked components) so you can cook later with minimal effort.

Ingredient Rules (with quantities/substitutions when given)

Rule 25 — Freeze milk in ice cubes

• Milk: “Half a pint of milk left”
• Portion size: each cube ≈ 2 tablespoons
• How to store: in a labeled bag (kept 3 months easy)
• Technique: leave a little gap at the top because milk expands when frozen

Rule 24 — Grate butter from frozen

• Butter: freeze a block
• Method: grate on the coarse side of a box grater
• Use for: scones, crumble, shortcrust pastry
• (No exact quantity given; it references a Tesco price/offer.)

Rule 23 — Freeze herbs in olive oil cubes

• Fresh herbs: parsley/coriander/rosemary/thyme (and basil mentioned)
• Medium: olive oil
• Method: chop herbs, pack into ice cube tray, cover with olive oil, freeze
• Use: drop into hot pan straight from frozen
• (Example: basil “stretched across six cubes”)

Rule 22 — Slice bread before freezing

• Bread: slice first
• Key prep: place a small square of greaseproof paper between each two slices
• Portions: “exactly two slices for toast” straight from frozen
• Timing: “3 minutes perfect toast”
• Thawing note: sandwich slice defrosts on the counter in 15 minutes

Rule 21 — Peel bananas then freeze

• Bananas: freeze peeled, brown spotty bananas
• Storage: lasts 6 months
• Baking benefit: sweeter/softer mash; freezing “breaks down cell walls”
• Substitution: “One frozen banana can even replace an egg in most cake recipes.”
• Equipment/technique: peel → bag → freeze
• Warning cue: don’t try to peel frozen bananas (takes a long time)

Rule 20 — Freeze leftover wine in ice cube trays

• Leftover wine: pour dregs into tray
• Portion size: 30 ml per cube
• Use:
  • Red: stews, shepherd’s pie, gravy
  • White: risotto, chicken/fish sauce
• Note: “The alcohol cooks off. The flavor stays.”

Rule 19 — Freeze hard cheese properly (grated)

• Cheese types: cheddar, red leicester, parmesan (hard cheeses)
• Method: grate first, then bag
• Use: sprinkle onto jacket potato/pasta/toast from frozen
• Texture note: crumbles a bit after thawing; not ideal for a cheeseboard, but fine for cooking/melting

Rule 18 — Flat-freeze mints

• Mince/mints: “500 g of mints”
• Method: press flat inside a freezer bag, push air out, freeze flat “like a book”
• Defrosting timing: flat pack ≈ 30 minutes vs lump ≈ 3 hours
• Buy/portion tip: “Buy four packs… flat freeze them all”
  • Context: batch for bolognese/chili/shepherd’s pie

Rule 17 — Freeze bread dough before baking

• Dough: big batch made into rolls/small loaves
• Prep: shape → freeze solid on a tray lined with greaseproof paper → bag
• Thaw/rise: “night before… move one portion to the fridge”; by morning it has defrosted and risen
• Timing: “20 minutes later, proper fresh bread”

Rule 16 — Batch cook curry paste (freeze in cubes)

• Base ingredients (blend): onions, garlic, ginger, chili, cumin, coriander, turmeric, and oil
• Cookdown: cook it down 15 minutes
• Freeze: spoon into ice cube tray
• Portion rule: “Freeze one cube per person”
  • (Alternative phrasing: “Two cubes and coconut milk makes curry for 2.”)
• Curry timing: curry ready in 20 minutes after cubes + coconut milk

Rule 15 — Freeze leftover gravy in muffin tins

• Leftover gravy: ladle into silicone muffin tin
• Freeze: pop discs out into a labeled bag
• Use: drop a frozen disc into hot pan
• Timing: “2 minutes” to be ready
• Texture cue: “No granules can touch it” (compared with packaged gravy)

Rule 14 — Pre-portion smoothie bags (7 days)

For each freezer bag:

• handful of frozen berries
• half a banana
• 1 tablespoon oats

• a spoonful of yogurt

• Method: seal and freeze flat

• Use: tip one bag into blender, add milk or juice, blend 30 seconds
• Breakfast timing: “Breakfast in 90 seconds”

Rule 13 — Freeze egg whites and yolks separately

• Egg whites:
  • freeze in ice cube tray
  • “one cube is one white”
  • label with how many
• Yolks:
  • add pinch of salt or half a teaspoon of sugar before freezing
  • label whether they’re for salty (pasta) or sweet (custard)
• Use: defrost needed amount for meringue/pavlova or other recipes
• Caution cue: yolks “otherwise, they go gluey”

Rule 12 — Open-freeze (individually quick frozen) veg/berries

Technique (IQF-style):

• spread items in a single layer on a tray
• freeze uncovered for two hours
• then bag so pieces don’t clump

Works for: berries, peas, diced peppers, sliced onions; also broccoli, mushrooms, carrots, courgette (“corettes” in the subtitles)

Outcome: pour out exactly what you need.

Rule 11 — Freeze cooked rice

• Cooling rule: cool the rice within 1 hour
• Method: portion into freezer bags, flatten
• Reheat: microwave from frozen with a splash of water for 2 minutes
• Result cue: “Fluffy every time”
• (Safety phrasing is qualitative: follow the two rules and frozen rice is “perfectly safe.”)

Rule 10 — Freeze pasta sauce in portions

• Homemade tomato sauce ingredients listed: onions, garlic, tinned tomatoes, basil, sugar, olive oil
• Method:
  • “Simmer down”
  • ladle into freezer bags and freeze flat
• Defrost/cook timing:
  • microwave defrost in 4 minutes
  • pan thaw in 10 minutes
• Taste cue: should taste like you cooked it (not “jar” taste)

Rule 9 — Make breadcrumbs from stale bread

• Method:
  • put stale ends into food processor
  • “blitz” into crumbs
  • bag and “shake the bag once a week to keep the crumbs loose”
• Use: fish fingers, chicken kievs, crumbled toppings, stuffing
• Tip: keep a dedicated crumb bag; crumbs improve stuffing by Christmas

Rule 8 — Freeze tomato paste in tablespoon dollops

• Tomato paste: example cited (90p tin)
• Method:
  • spoon tablespoon dollops onto a lined tray
  • freeze solid → bag
• Use: grab single portion for recipes needing a tablespoon
• Storage claim: lasts 2 months

Rule 7 — Freeze stock in cubes/portions

• Stock (from roast chicken carcass):
  • simmer carcass with onion, carrot, celery, peppercorns for 3 hours
  • strain → cool → freeze
• Portion formats:
  • ice cube trays for small amounts
  • bigger containers for soup bases
• Store-bought comparison: shop stock tastes like “slightly flavored water,” while homemade has “body, richness, and depth.”

Rule 6 — Freeze leftovers in (saved) takeaway containers

• Method:
  • save plastic takeaway containers; wash
  • must be microwave safe, freezer safe, and stackable (as stated)
  • portion cooked leftovers (chili/stew/curry/soup), label, stack
• Serving cue: use later as quick ready meals (no specific reheating time given)

Rule 5 — Freeze double cream after whipping

• Method:
  • double cream whip to soft peaks
  • pipe/dollop small portions onto a line tray
  • freeze solid → bag
• Uses: hot chocolate, scones, puddings, trifles
• Melts well on warm dishes (soup bowl, apple pie slice, mug of cocoa)

Rule 4 — Freeze ginger and garlic

• Method: freeze whole ginger and garlic; grate straight from frozen
• Cues:
  • no peeling ginger (“skin grates away to nothing”)
  • garlic cloves grate straight into a hot pan
• Benefit statements: fresher/sharper than pre-minced jars, less waste, easier on hands

Rule 3 — “Yellow sticker” meat: freeze immediately

• Method/cue:
  • reduced fresh meat (yellow sticker) is meant to be eaten or frozen the same day
  • “Freeze immediately” is the key rule
• Timeframe given: “3 months in the freezer at full quality”
• Context claim: supermarkets reduced meat by 50–75% at day of cell-by; video says reduction timings changed (smaller stickers) to reduce “savvy shoppers’ impact.”

Rule 2 — Sunday batch cook system (freeze full meals)

• Time: “Spend three hours on a Sunday”
• Cook 3–4 big meals (examples: chili, bolognese tray, chicken casserole, vegetable soup)
• Method: portion into containers, freeze everything
• Output: “15 to 20 meals for the next 2 to 3 weeks”
• Goal: reduce weekday decision-making, cooking, and washing up

Rule 1 — Freezer inventory list (rotation to prevent waste)

• Method:
  • write down every item on a list pinned to freezer door
  • use pen/paper + blue tack
  • update when items go in/out
  • cross items off as used; add new items
• Rotation rule:
  • “Every single time something goes into the freezer, something comes out for the next meal.”
  • Also: “Bin anything over 6 months old” (stated in the audit step below)

“Audit” / Freezer Organization (included between Rule 18 and Rule 17)

• Fix (takes 20 minutes):
  • pull everything out
  • group into categories (meat shelf, vegetables shelf, etc.)
  • label with date
  • bin anything over 6 months old
• Result cue: find forgotten items and stop duplicate buying.

Equipment Mentioned

• Ice cube tray(s)
• Freezer bags (and writing/labelling tools)
• Box grater (coarse side)
• Food processor (for breadcrumbs)
• Silicone muffin tin (for gravy discs)
• Blender (for smoothie bags)
• Tray lined with greaseproof paper (freezing dough/bread and tomato paste dollops)
• Line tray for open-freezing veg (IQF method)
• Freezer door list supplies: pen, paper, blue tack

Key Technique Cues / Timings / Temperatures (as stated)

• Open-freeze items: 2 hours uncovered
• Flat-freeze mint defrost: 30 minutes vs lump 3 hours
• Bread toast: 3 minutes
• Sandwich slice counter thaw: 15 minutes
• Microwave reheat rice: 2 minutes (from frozen + splash water)
• Microwave portion sauce thaw: 4 minutes; pan thaw: 10 minutes
• Gravy disc pan heat: 2 minutes
• Smoothie blend: 30 seconds
• Dough: fridge overnight, then bake 20 minutes later
• Curry paste cookdown: 15 minutes
• Chicken stock simmer: 3 hours
• Cooling: cook rice should be cooled within 1 hour before freezing

Chef Tips / Common Mistakes to Avoid

• Don’t treat the freezer like a cupboard; overstuffing leads to buried/forgotten food.
• Don’t pour off leftover milk or throw stale bread away—use freezing methods.
• Don’t freeze some items incorrectly:
  • bananas: peel before freezing
  • egg yolks: add salt or sugar before freezing (otherwise “gluey”)
  • hard cheese: grate before freezing (for later melting)
  • open-freeze veg: freeze uncovered first so pieces don’t clump
  • for bread: slice first and separate slices with greaseproof
• Rotation is essential:
  • inventory list + “one in, one out” prevents graveyard build-up.

Plating / Serving Suggestions (when stated)

• Milk cubes for tea/coffee/white sauce
• Herb oil cubes: drop into a hot pan straight from frozen; use for maintaining green color
• Cheese: sprinkle from frozen onto jacket potato/pasta/toast
• Gravy: pop a frozen disc into a hot pan for quick midweek gravy
• Double cream: dollop onto warm soup, apple pie slice, or cocoa for melting
• Tomato paste: use one tablespoon cube in stews/soups

Variations Discussed (concise)

• Wine cubes:
  • Red → stews/shepherd’s pie/gravy
  • White → risotto/chicken or fish sauce
• Egg freezes:
  • whites → freeze as cubes; defrost needed amount for meringue/pavlova
  • yolks → freeze with salt (savory) or sugar (sweet); label accordingly
• Herbs in oil: chop and freeze in olive oil cubes; use straight into hot pan
