Friends sharing a revision break at home
Think about how many biscuits the group is likely to eat before choosing between the listed 200 g, 300 g and 400 g packs. Check the storage directions if some will be left over.
Who is sharing?
Parents planning revision snacks
Compare portions and per-biscuit sugar figures for the pack you intend to serve. A snack bought for home is a different decision from food provided at school.
People organising a group with allergies
Check the current ingredient and precautionary allergen information for everyone sharing. The listed standard recipes include wheat and milk, while other allergen statements vary by product.
What should you check?
| Priority | What to check | Your needs |
|---|---|---|
| Amount to share | Compare pack weight with any stated biscuit or serving count. ASDA Groceries suggests 34 servings for its 400 g pack; Tesco Groceries lists 400 g, and Sainsbury’s lists 200 g. A suggested serving is not necessarily one biscuit. | We need enough for the group, but I would rather not open a larger pack than we are likely to use. |
| Sugar and portions | Use the same nutrition basis when comparing recipes. Tesco Groceries lists 3.4 g total sugars per biscuit for its 400 g pack; Sainsbury’s lists 3.3 g per biscuit for its 200 g pack. Check how many biscuits you plan to put out. | I want to decide on a portion rather than use pack size alone to choose the snack. |
| Allergens | Read the ingredients and precautionary statements on the exact pack. The listed Tesco and Asda recipes contain wheat and milk; Tesco also notes possible sesame. | Someone sharing may need to avoid an ingredient, so I cannot rely on a different pack’s label or a vegetarian description. |
| Leftover storage | Check the opened-pack instructions before choosing a larger quantity. ASDA Groceries directs shoppers to use an airtight container once its custard creams are opened. | If the group will not finish the pack, I need somewhere to store the remaining biscuits as directed. |
Common buying mistakes
-
Assuming “sharing” means a set number of portions
The listed packs range from 200 g to 400 g, and sellers use their own suggested serving counts. Pack weight alone does not tell you how many biscuits each person wants.
Estimate the group’s likely biscuit count, then compare pack weight, any stated count and the storage directions.
Biscuits left in an opened pack may need an airtight container, as directed on the Asda listing.
-
Choosing by pack size without checking the recipe
Marks & Spencer lists 40.2 g total sugars per 100 g for its Extra Cream 165 g biscuits, compared with 26.5 g per 100 g on Sainsbury’s 200 g listing. The M&S ingredient list also includes soya lecithin.
Compare nutrition on the same per-100 g basis and check the current allergen label for the recipe you choose.
-
Treating a home snack like school-provided food
For food provided to pupils by covered schools in England, Department for Education school-food standards distinguish lunch from food provided outside lunch; the standards do not allow biscuits as food provided outside lunch.
For a school-run revision session, check the school’s arrangements and the rules applying to its nation and setting rather than using a home-shopping decision as the answer.

Questions about sharing custard creams
How should I store biscuits left after a revision break?
Follow the directions on your pack. The checked Tesco Groceries and ASDA Groceries listings direct shoppers to keep their biscuits in a cool, dry place and use an airtight container once opened.
Does “suitable for vegetarians” mean suitable for someone with a milk allergy?
No. The vegetarian-labelled Tesco and Asda custard creams listed here both contain milk ingredients. Check the current ingredients and precautionary allergen information for the exact pack before sharing it.
Can a school provide custard creams at a revision session?
For food provided to pupils by covered schools in England, Department for Education school-food standards distinguish lunch from food provided outside lunch: biscuits are allowed at lunchtime but not as food provided outside lunch. A private break at home is different. For a school-run session, check the school’s arrangements and the rules applying to its nation and setting.
