Cornbread a skill trade food of 4 different varrying ingredients, corn, seasoning blend, cauliflower, and salt.
cornbread increases your luck when harvesting by 1400 for 25 minutes.
I just made a bunch of different trade foods, and the wild berry compote (arcana skill food) gave 450 exp for 3 of them. while Cornbread only gives 43 exp. The same is for the herb roasted potatoes and therefore i’m going to assume the other skill food as well.
