How do you say The proof is in the pudding in Latin?

Answer 1

You don't. There is no such expression. The expression is "The proof of the pudding is in the Eating ( or tasting)." Proof in this sense means "test." So what we want to say in Latin is "The test of the food is the taste," or something like Sapor cibi temptatio.

To maintain the sense and the alliteration:

Signum in sanguiculo est.
