Didn't see this until now, but I do Kahlua Candied Yams which can be done a day ahead. I do these for New Years with a herb rubbed pork roast and collards.
One small sweet potato per person.
Wash sweet potatoes.
Cover with water and cook just until a fork will barely go in.
Peel, cut into one inch rounds and drop into prepared syrup.
*Sauce for five sweet potatoes.
In large skillet melt one stick butter.
Add 1/2 cup brown sugar and one cup kahlua.
(You can add 1/2 cup drained pineapple bits or coursly cut pecans. You may have to increase the syrup)
Simmer on low fifteen minutes to form a syrup.
Simmer 20 minutes with potato rounds, spooning syrup over frequently.
I have a white oven mit and I peel and cut the potatoes in my hand and let them fall in the warm syrup.
Gets better the next day. Can be warmed in the microwave.
Alcohol cooks out.
