Mixing curd (yogurt) and lemon juice isn't inherently dangerous, but it's not always ideal. The combination can cause digestive upset for some people.
Understanding the Issue
Both curd and lemon are acidic. Combining them increases the overall acidity, potentially leading to an imbalance in stomach pH. This can result in symptoms like indigestion, heartburn, or an upset stomach. [Reference: 12-Nov-2023 source - Citrus fruits like oranges, grapefruits, and lemons are high in acidity. Combined with curd, which is also acidic, it can lead to an imbalance in pH levels in the stomach. This may result in indigestion, heartburn, or an upset stomach.]
However, the effect varies from person to person. Some individuals might tolerate the mixture without issue. The amount of lemon juice added also matters; a small quantity might not cause any problems.
Culinary Uses: Lemon and Curd
While mixing curd and lemon directly may not be advisable for everyone due to potential digestive upset, it's crucial to note that lemon curd, a popular culinary creation, uses both lemons and eggs (which can be considered a base similar to curd). This culinary combination uses heat, emulsifiers and a different process, hence its difference from simply mixing curd and lemon together.

Conclusion:
While you can mix curd and lemon, it's not always recommended due to their combined acidity which can potentially upset some individuals' stomachs. The use in lemon curd recipes demonstrate that a careful and controlled process can create a different result.
