There isn’t really a recipe, it is old deep South, handful of this and that!
Start off with a quart of good vanilla ice cream, I use a recipe with eggs, cream and milk, scalded plus vanilla and sugar into the ice cream maker. Or you could start with a large tub of best ice cream already made.
Part freeze and then add, chopped pecans, chopped angelica, flaked sweetened coconut (NOT dessicated) and brandy, no more than 3-4 tablespoons per quart otherwise you screw up the freezing temp abd get slurp instead. Freeze hard, pack in a box and leave to firm up for a day or so. You would need a good handful of each addition.
If you need a good ice cream basic recipe let me know and I’ll dig mine out.
How the Confederates managed to lose with ice cream like this defeats me utterly!
