Are there any available substitutes for greek yogurt?
I don't have any in the fridge. Looking for a substitution besides regular yogurt or any yogurt based substitution. Looking to make a creamy like cold sauce for fish tacos.
Sour cream could work. It has a similar flavor to plain greek yogurt, although the consistency is somewhat different. In fact, My fiance and I have switched to using greek yogurt in place of sour cream because of this since sour cream is higher in calories. I think it would be just fine for a sauce.
For cooking, or putting a dallop on top of a bowl of soup? Try crème fraiche.
Greek expat here; while roaming in various countries, I often stumble across yogurt variants that tend to be too liquid for my taste ;)
Here is what to do in that case: take said yogurt and pass it through fine cloth (typically this is a clean/unused kitchen towel). Discard the liquid and keep the now much thicker yogurt for your needs. Hint: this works brilliantly for preparing tzatziki!
Advice: never fail to buy some greek yogurt when you find it available, as a minimum to use it as reference in thickness/taste for whatever else you want to compare with! Also, remember, higher price may just imply quality.
