What can I use as a substitute for buttermilk in baking? I live in Bombay and it's hard to come by
You can use whole milk and add about a teaspoon of lemon juice or vinegar to sour it.
If you feel like making buttermilk - and butter: authentic buttermilk comes from whipping cream until it separates, so you'll have homemade butter and homemade buttermilk.
Most commercial buttermilk is just skim milk with thickening agents in it. True buttermilk is low in fat and much different. If this brand is near you, I've tried it and it's wonderful!
I like to use half milk and half lain Greek yogurt
I mean plain Greek yogurt
Thanks for answers! I was confused because in India we make masala buttermilk by combining milk and plan yoghurt, wasn't sure if I could use that. I am going to try darksideofthespoon's technique as well. All these techniques are easy and accessible! Thanks much.
@darksideofthespoon " Most commercial buttermilk is just skim milk with thickening agents in it." This isn't quite true. Modern commercial buttermilk is a cultured product, like yogurt or creme fraiche. It is the acid produced by the bacteria which thickens the milk by partially coagulating the proteins. Because of this, modern recipes which rely on the acid content of commercial buttermilk CANNOT be made with traditional buttermilk (as left over after butter making), which is not sour enough.
If you don't have buttermilk, you can add 1 1/2 tsp (8ml) lemon juice or white vinegar to one cup milk; stir well and let stand 5 minutes. It won't be as thick as the commercial stuff, but will taste close enough to be useable.
I whisk nonfat milk with plain nonfat yogurt....
