I have not seen this specifically, but I do see cute things in mason jars, and once ate a pudding out of a mason jar in a restaurant. I can assure you, it all looks very cute but is cumbersome to eat. Digging the spoon into the jar is clumsy and messy. It’s a better theory than reality. Pinterest has tons of things in mason jars, trust me, TONS. Very cute, very homey looking, very “Walton family” but the reality is different.
