For a Mexican-style sauce, consider an unsweetened soya drink if you do not want sweetness, but compare the fat and sugars on the exact carton rather than assuming that ‘unsweetened’ or ‘light’ means lower fat. A reduced-fat drink may suit a preferred product, but neither label means the drink will replace cream in a recipe; soya drinks can separate during cooking, so heat gently.
Who is this for?
Mexican-night cooks comparing fat and sugars
If a soya drink is going into a sauce or served alongside the meal, the nutrition panel helps you choose between unsweetened and reduced-fat options. Cooking behaviour matters separately: a drink is not necessarily a substitute for cream.
Hosts serving guests who avoid dairy
A soya drink offers a plant-based option, but dairy-free does not mean allergen-free. Check the carton and other ingredients in the meal if a guest has a soya allergy.
Shoppers planning the meal ahead
A long-life carton can be bought for a future dinner. Check how it must be stored after opening, particularly if the recipe uses only part of it.
What should you check?
Choose for the recipe first, then compare nutrition figures on the same stated basis and check storage and allergens before serving.

What to check |
Your needs |
| Fat and sugars |
Read fat, saturates and sugars on the exact carton. Compare figures stated per 100ml with other per-100ml figures; M&S states its figures per 100g, which is a different basis. Sainsbury's lists 1.3g fat and less than 0.5g sugars per 100ml for its Unsweetened Soya Drink. |
I want to compare what is in the drink, rather than choose solely because its name says ‘light’ or ‘unsweetened’. |
| Sauce texture |
Check whether the particular drink is described for savoury cooking. Tesco's listing presents Alpro Soya No Sugars for savoury dishes; Waitrose advises gentle heating because its soya alternative can curdle or separate. Neither statement establishes that a soya drink will behave like cream. |
If I am stirring it into a Mexican-style sauce, I need a milk-like ingredient that fits the recipe, without counting on a cream-like finish. |
| Ingredients and fortification |
Read the exact carton's allergen statement and listed nutrients. Sainsbury's, M&S and Waitrose describe fortification on their unsweetened products, but their formulations should not be treated as identical. |
I am serving other people, so I need to know whether the drink contains an ingredient they cannot have and what is listed on this particular pack. |
| Storage |
Check whether the carton is chilled or long-life, then follow its instructions after opening. The Sainsbury's and Waitrose products described here state refrigeration and use within three days of opening. |
For a dinner later in the week, I want a carton I can store as planned and use within its stated period once opened. |
What could go wrong?
-
Assuming ‘light’ means the least fat
‘Light’ and ‘unsweetened’ describe different features. For example, Sainsbury's lists 1.3g fat per 100ml for its Unsweetened Soya Drink, while its Alpro Soya Light listing describes a reduced-fat product; the names alone do not establish which carton has less fat.
Compare the nutrition panels of the exact products you are considering, using the same stated measurement basis.
-
Boiling a soya drink in the sauce
Waitrose warns that its soya alternative can curdle or separate during cooking, changing the sauce's texture.
Stir it in over gentle heat and take the pan off the heat before boiling. Try a small amount in the recipe before relying on it for a shared meal.
-
Equating dairy-free with allergen-free
The Food Standards Agency identifies soya as an allergen. It may also be present in other ingredients served with the meal.
If someone has a soya allergy, do not serve them a soya drink; check the labels of sauces and other packaged ingredients too.
-
Overlooking instructions after opening
A carton kept for a planned dinner may need different storage once opened. The Sainsbury's and Waitrose drinks described here state that they should be refrigerated and used within three days of opening.
Check the instructions on your carton before opening it, especially if you expect to use only part of it in the recipe.

Common questions
Can soya drink replace cream in a Mexican-style sauce?
Not as a one-for-one assumption. Tesco presents Alpro Soya No Sugars as suitable for savoury dishes, but Waitrose warns that soya alternatives can separate in cooking. Use a soya drink where the recipe calls for a milk-like liquid, heat it gently and choose a product intended for cream-like use if that texture is essential.
Is unsweetened soya drink always lower in fat than a ‘light’ one?
No. The words describe different features, so compare the exact nutrition panels. Sainsbury's lists 1.3g fat per 100ml for its Unsweetened Soya Drink; M&S states 1.4g per 100g for its unsweetened drink. Those figures use different measurement bases.
Is soya drink suitable for a guest with a soya allergy?
No. The Food Standards Agency identifies soya as an allergen. Check every packaged ingredient in the meal, including sauces and meat alternatives, rather than assuming a dairy-free recipe is free from soya.
How should I keep a carton opened before Mexican night?
Follow that carton's storage instructions. The Sainsbury's and Waitrose products described here both state that they should be refrigerated after opening and used within three days.
Can an unsweetened soya drink be a child under two's main milk drink?
Do not assume so. Sainsbury's states that its Unsweetened Soya Drink is not suitable as a main milk-drink alternative for children under two. Check the guidance on the exact product and seek professional advice for a child's individual dietary needs.
