Great responses from all...I can't add much as I do not have kids but I do remember my sister would never eat mashed potatoes as a kid - texture thing. Now...please don't get between her and a bowl of them!!!
As a teen I would always make my grandfather his favorite liver every other month or so and try it....still can't eat it. While working in a kitchen I had to have my boss taste the country chicken liver as I could not choke it down. Tonight I am trying eggplant(again). I have never liked it but found a new recipe to try and maybe I will like it. If not - I have a vegetarian friend who will appreciate it .
oh....and salmon. I have tried it canned, fresh in WA state, smoked. Uh, noooooooooo
EDITED to say...uh, no go on the eggplant. The marinara and cheese were good, especially over bucatini with sautéed zucchini but the eggplant😜
