Buttermilk: what every chef needs to know
Think Buttermilk and you are looking at a dairy product that originally arose as a by-product of churning butter: the remaining liquid after the butter fat was removed. Modern buttermilk is almost always "cultured": pasteurised skimmed milk acidified with lactic acid bacteria to produce a lightly thickened, sour drink. Fat content is low (approximately 0.5–1%), and the lactose content is lower than in fresh milk as the bacteria convert lactose to lactic acid. Buttermilk's specific acidity is important as a leavening agent in baking: the combination of buttermilk and bicarbonate of soda (baking soda) produces carbon dioxide that raises dough without yeast. In commercial kitchens, buttermilk is used in pancake batter, scones, soda bread, chicken marinades (tenderising), salad dressings and cold soups. The light acidity gives dishes a fresh, complex flavour.

Frequently asked questions about Buttermilk
Can I substitute something else for buttermilk in a recipe?
Yes: add 1 tablespoon of white wine vinegar or lemon juice to 240 ml whole milk and leave for 10 minutes. The milk will lightly curdle, mimicking the acidity of buttermilk. For every 100 ml of buttermilk: 98 ml milk plus 2 ml vinegar. This works well for baking but lacks the subtle bacterial flavour of real buttermilk.
Why does buttermilk make chicken so tender?
The lactic acid in buttermilk has a mild proteolytic effect: it begins to break down the outer muscle proteins in the meat, softening the texture. The viscosity of buttermilk also helps herbs and spices adhere better to the surface of the chicken for coating and frying.
What is the difference between traditional and cultured buttermilk?
Traditional buttermilk is the by-product of butter churning: thinner, less sour and with small fat particles. Cultured buttermilk is skimmed milk artificially acidified with bacterial starters and is thicker, more sour and homogeneous. Virtually all supermarket buttermilk is cultured. Traditional buttermilk is barely commercially available any more.
At what temperature should you store Buttermilk?
Store Buttermilk at 2°C to 6°C, compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.
How do you prepare Buttermilk professionally?
The primary professional technique for Buttermilk is Marinade for chicken of pork at koud, 4-24 uur in koeling for minimaal 4 uur. Always verify core temperature with a calibrated probe thermometer.
Does Buttermilk contain allergens?
Buttermilk contains: Milk. Declaration required under EU Regulation 1169/2011 Annex II.

Informational character
The information on this page has been compiled exclusively as reference material for professional kitchen staff. KitchenNmbrs does not provide legal, medical or commercial advice. Data on preparation techniques, storage temperatures, HACCP guidelines and allergens is based on publicly available professional sources and applies to the raw ingredient in its unmodified state.
Your responsibility as operator (FBO)
Under EU Regulation 1169/2011 (Food Information Regulation) and EU Regulation 852/2004 (HACCP Hygiene Regulation), the Food Business Operator (FBO) is solely and exclusively responsible for:
- Providing accurate, up-to-date and complete allergen information to the end consumer;
- Determining allergens in the finished product based on current supplier documentation;
- Maintaining and documenting a demonstrable HACCP management system;
- Controlling cross-contamination risks within their own production environment;
- Compliance with local food safety authority requirements.
Allergen information: Limitations
The allergen information on this page relates to the ingredient as such. The actual allergen composition of your purchase may differ due to:
- Varying suppliers, production facilities or growing regions;
- Cross-contact during production, transport or storage ("may contain");
- Changed product formulations not yet reflected in public sources;
- Processing or preparation in your own kitchen that introduces new allergens.
Always verify allergens against the current specification sheets (spec sheets) from your supplier. Orally or informally provided allergen information is not legally valid under EU Reg. 1169/2011.
Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
Limitation of liability
KitchenNmbrs B.V. excludes all liability for direct or indirect damages arising from:
- Use of the information on this page as the basis for commercial or operational decisions;
- Allergic reactions, food poisoning or other health incidents involving guests or staff;
- Inaccuracies resulting from changed product compositions by third parties (suppliers);
