For a savoury Sunday roast, start by checking an unsweetened soya drink’s label and cooking instructions rather than choosing a multipack by quantity alone. Waitrose advises heating its unsweetened drink gently and taking it off the heat before boiling; if you are stocking up, also check how quickly you can use each carton after opening. For regular use as a dairy alternative, compare fortification on the exact product label.
If you are making gravy or another hot savoury sauce, look for an unsweetened carton and read its cooking instructions. Waitrose advises gentle heating for its Essential Unsweetened Soya Drink because soya alternatives can curdle or separate.
Long-life cartons can be bought for later use, but opening one starts its refrigerated use period. Compare the size of each carton with how much your household will use: the Waitrose Essential and M&S unsweetened examples specify three days after opening, while Plenish Organic Soya specifies four.
If fortification matters to your choice, check the exact carton for calcium, iodine, vitamin D and vitamin B12. NHS guidance for a vegan diet recommends considering fortified dairy alternatives; soya drinks do not all have the same ingredients.
Choose a drink that fits the roast dish first, then check its carton size, storage instructions and label before deciding how many to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Savoury cooking | Check whether the drink is unsweetened and read its heating instructions. Waitrose advises heating its Essential Unsweetened Soya Drink gently and removing it from the heat before boiling. | I’m making gravy or a sauce and want to avoid an unexpected sweet flavour or a drink that separates during cooking. |
| Fortification | Read the exact carton for added calcium, iodine, vitamin D and vitamin B12. NHS guidance discusses fortified dairy alternatives for a vegan diet; the listed Waitrose Essential and M&S unsweetened drinks include these nutrients, while the Plenish Organic Soya listing describes a two-ingredient drink. | If soya drink regularly replaces dairy in my household, I want to know what is added to the one I buy. |
| Carton size and storage | Check the number and size of cartons, then follow each product’s refrigeration and use instructions after opening. Waitrose Essential and M&S Unsweetened specify three days; Plenish Organic Soya specifies four. | For an occasional roast, I’d rather open only a carton I can use within its stated period. |
| Ingredients and allergies | Read the ingredients and allergy advice on the carton you receive, particularly if someone eating the roast has a relevant allergy. M&S says product information can change and flags a nut and peanut allergy restriction for its unsweetened drink. | I need to check that the current recipe is suitable for everyone at the table. |
Soya alternatives can curdle or separate during cooking, according to Waitrose’s guidance for its Essential Unsweetened drink.
Check the chosen carton’s instructions. For the Waitrose product, heat gently and remove the pan from the heat before boiling; try a small amount in the sauce before making a larger batch.
A carton’s unopened format does not extend its stated period of use after opening. The Waitrose Essential and M&S unsweetened examples specify three refrigerated days, while Plenish Organic Soya specifies four.
Before buying several cartons, check each one’s size and plan when you would open and use it.
The listed Waitrose Essential and M&S unsweetened drinks include added nutrients, whereas the Plenish Organic Soya listing describes a drink made from spring water and organic soybeans.
If fortification matters for regular use, compare the exact labels for calcium, iodine, vitamin D and vitamin B12 rather than relying on the word ‘soya’ or ‘organic’.
M&S warns that recipes and allergen information can change, and its unsweetened soya drink carries a nut and peanut allergy restriction.
Read the ingredients and allergy advice on the physical carton each time, including when a familiar product has new packaging.

For a savoury roast sauce, this no-sugars variant is worth considering if the current carton’s cooking instructions suit your recipe. The pack contains eight separate 1-litre long-life cartons; check the label for fortification and how soon to use each carton after opening.
An unsweetened drink is a sensible starting point for a savoury sauce, but follow the chosen carton’s cooking instructions. Waitrose advises heating its Essential Unsweetened Soya Drink gently and removing it from the heat before boiling because soya alternatives can curdle or separate.
Not necessarily. Waitrose lists Plenish Organic Soya as spring water and organic soybeans, while the listed Waitrose Essential and M&S unsweetened drinks have added nutrients. Check the exact carton if fortification is part of your buying decision.
Follow the period on that carton: the listed Waitrose Essential and M&S unsweetened drinks specify refrigeration and use within three days, while Plenish Organic Soya specifies four days. Buying a multipack does not change the instructions for a carton once opened.
Read the ingredients and allergy advice on the physical carton before using it. Soya drinks contain soya, and M&S also flags a nut and peanut allergy restriction for its unsweetened drink; product information can change.
Compare the exact products’ ingredients and fortification rather than assuming all soya drinks are alike. NHS guidance for a vegan diet discusses fortified dairy alternatives and identifies vitamin D, vitamin B12, iodine and calcium as nutrients that may need attention.
