Plain yogurt

Taste and Texture

The flavor is mild with a subtle tang, and depending on the product, the milk-like taste and creaminess vary. Even unsweetened varieties have natural acidity from fermentation, which helps cut richness in savory dishes and highlight sweetness. Regular plain yogurt is soft enough to scoop with a spoon, but products where whey has separated may feel thinner. For dips or creams requiring a thicker texture, a thick yogurt is favorable, while thinner products can increase batter and sauce moisture like water or milk.

Main uses

• Mix with cucumber, herbs, garlic, and salt to make cold dips or accompaniments. If you add high-moisture vegetables directly, they become thinner over time, so when a richer sauce is needed, pat vegetables dry first.
• Add to curries, stews, and soups to contribute acidity and a soft texture. When added all at once while boiling, separation can occur, so it is better to reduce heat and add gradually while stirring.
• Use in marinades for meats such as chicken or lamb to help the spices adhere and impart a soft texture on the surface. If marinated too long, the surface can feel too soft, so this is not suitable for very thinly sliced ingredients or delicate fish.
• Add to cake, muffin, or pancake batters to contribute moisture and a light acidity. When substituting some of the liquid in the batter, adjust other liquids slightly based on the yogurt's thickness to avoid making it too thin.

Preparation tips

• If the whey sits on top before using, mix it in as is to achieve uniform thickness, or strain only when you want a firmer result. Note that mixing in the whey keeps flavor but increases moisture in sauces and batters.
• When adding to hot broths or sauces, whisk in warm liquid gradually with yogurt to raise the temperature before adding to the pot. This helps reduce lumps from rapid temperature changes.
• For cold sauces, don't add salt and acidity all at once; mix and let sit briefly, then taste. Salt can draw moisture from vegetables, so if a sauce with cucumber or tomato becomes thin, adjusting the vegetable's moisture is preferable to adding more yogurt.
• When baking, let the yogurt sit briefly to mix well with other ingredients rather than adding cold yogurt directly. However, if the dough needs to hold butter firmly, room-temperature yogurt can raise the dough temperature if left out too long.

Cooking characteristics

• Plain yogurt adds a soft texture and acidity to sauces at low heat, but long simmering over high heat can cause proteins to coagulate and separate into whey and curds. When bubbles form on the surface and grains appear, immediately reduce heat or remove from heat and stir.
• Higher-fat, creamier yogurts tend to resist separation during heating, but no product remains perfectly stable under vigorous boiling. For smooth finishes in cream sauces, it is safer to use yogurt in the finishing stage rather than as a long-cooked main ingredient.
• In batters, yogurt's acidity can interact with leavening agents to affect texture. If the recipe includes baking soda, yogurt's acidity can be particularly influential, so replacing with milk may yield less fluffy results or a different taste.
• Cold yogurt can become thinner when stirred; if a dip is thin from the start, continuous stirring makes it hard to restore thickness, so add additional liquid gradually.

Good combinations

• Fresh herbs like garlic, dill, mint, and parsley enhance the yogurt's acidity and pair well with cold sauces.
• Pair with mild or starchy ingredients like cucumber, roasted eggplant, potatoes, or chickpeas to lighten the yogurt’s heft.
• Warm aromatic spices such as cumin, coriander seeds, paprika, and pepper balance the yogurt's soft acidity. In very spicy dishes start with small amounts to ensure the acidity does not overwhelm the flavor.
• With honey, fruit, or nuts, it can be used for simple desserts or breakfast bowls. If fruit is very tart, taste after combining with yogurt’s acidity first before adding sweetness.

Points to consider when substituting

• For cold dips or dressings, sour cream can be used, but sour cream is generally richer and its acidity may differ. When substituting with a thinner plain yogurt, adjust the thickness with a small amount of water or milk.
• In heated curries or sauces, creme fraiche or similarly thick cultured dairy can feel more stable, but flavors will be richer and less light. Yogurt's bright tang is key in some dishes, so it may not be a complete substitute.
• Baking can use buttermilk to provide similar acidity and moisture, but it will be much thinner. When replacing yogurt with buttermilk, consider reducing other liquids or adjusting batter thickness.
• If dairy must be avoided, plant-based unsweetened yogurt can be considered, but its protein and fat composition differ, affecting thickness and separation on heating. It is easier to apply in cold sauces, but for hot sauces or baking where coagulation stability is important, small tests are more appropriate.
