While the next episode is rendering, here's the best crockpot recipes, for reference:
Meatballs -
One morsel of any sort, three filler (including ice but not twigs). Also, monster meat and 3 filler works as well. Fills 62.5 hunger, 3 health and 5 sanity.
Meaty Stew -
Meat value of 3 (morsels/drumsticks count 0.5), any filler other than honey, twigs, moles, mandrakes or tallbird eggs.
For example, meat, monster meat, morsel, morsel would make the stew. Fills 150(!!) hunger, 12 health, 5 sanity.
Turkey Dinner -
two drumsticks, a meat filler and either a fruit or vegetable.
For example, two drumsticks, monster meat, berries. Or two drumsticks, morsel, carrot. Fills 75 hunger, 20 health, 5 sanity.
Trail mix -
A roasted birchnut, one unit of berries, one fruit based filler (another berries would work) and a twig. Doesn't really sate hunger (12.5), but restores 30 health. 5 sanity.
Dragon Pie -
If you get a dragonfruit from your farm (it's rare), cook it with 3 twigs. Restores 75 hunger, 40 health, 5 sanity.
Honey Ham -
Monster meat, 2 morsels and one honey. Restores 75 hunger, 30 health, 5 sanity.
There are lots more recipes, but these are the most convenient/efficient ones I found.
