Milk + Buttermilk
A cook's pairing more than a chemical one: 9 recipes use both, though they share little aroma. They rank in the top 41% of all ingredient pairs.
Do milk and buttermilk go together?
Yes, in practice. 9 recipes in our collection combine them, and they share 50 flavor molecules. That places them in the top 41% of every ingredient pair we score.
What they have in common
Almost everything buttermilk carries, milk has too: 50 of buttermilk's 52 flavor molecules also occur in milk. Among the shared key aromas are 1-octen-3-ol (mushroom, earthy) and ethanol (alcoholic, ethereal). So the pairing rests more on how cooks use them than on shared aroma.
What each one brings

Recipes with milk and buttermilk
Almost always mains: 5 of the 5 recipes with a course label are mains.
Can you swap one for the other?
Only partly. Almost all of buttermilk's flavor molecules (50 of 52) are also found in milk, but milk has 296 that buttermilk lacks. Buttermilk gives you part of milk's character without most of its fruit. This compares flavor only; texture, moisture and the job each does in a dish matter too.
