Agree with the minimal and normal ingredients as well. Last night we had chicken thighs in the fridge. I looked up in Appetite - recipe was called "chicken, garlic, herbs".
The sum total of the ingredients was: chicken, garlic (whole and unpeeled), herbs (choice of long list so I used what I had), butter/olive oil, salt, and pepper.
I did one of the variations and added white wine, a splash of cream which we had for strawberries anyway, tarragon and a squeeze of lemon.
Out of interest, Delia's tarragon chicken includes all the above plus sherry vinegar (don't have), creme fraiche (never buy) and 12 whole peeled shallots nightmare. Jamie's has all that again, but also mirepoix, bay leaves, stock, egg yolks, flour and button mushrooms!
