The skin of the chicken was nicely browned but not crispy (but not unpleasant) and the meat was very tender.
I followed the directions fairly closely but I did not bother browning the skin before simmering in Coke and I also used both drumettes and wings (The original recipe only used drumettes).
Chicken wings, 6 each wings and drumettes
Coca-Cola, regular, 1 bottle (16 fl oz or about 500 ml)
Garlic, 2-3 cloves
Japanese small whole dried red pepper, seeds removed, 2
Salt, 1/2 tsp
Sake 4 tbs
Soy sauce 5 tbs + sugar 2-3 tbs (I did not add sugar since Coke, to me, is very sweet.. a 12 oz can/bottle contains 52grams of sugar!).
1. Brown skin in a frying pan with olive oil (I did not see the point of make skin brown before simmering in liquid and omitted this).
2. Add the Coke and sake to the chicken wings in the frying pan. Skim off any scum (for some reason, "scum" developed immediately when the Coke mixture was added. After the scum is removed, add soy sauce and cover the pan with aluminum foil which was shaped to fit the opening of the pan.
3. Simmer for 30 minutes.
4. I let it cool to room temperature.
5. Since I was not ready to eat the chicken I put the simmering liquid and the chicken wings in a sealable container and in the refrigerator.
6. A few days later, I removed the chicken wings from the marinade and grilled them in the toaster oven for 10-15 minutes or until the skin was nicely browned.
This is rather good. Coca Cola* contains acid (phosphoric acid) which apparently tenderized the meat. The other ingredients added flavor. Compared to the other grilled chicken wings we make, the meat of this one is very tender with a nice sweet and sour flavor. If you divide up the simmering and baking steps for different days, as I have done here, you can enjoy baked/grilled chicken wings very quickly even on a workweek evening. I wonder if I cook the wings in black vinegar, soy sauce and mirin mixture, will the effect be similar.
