Try it yourself - Trifle can be an incredibly easy, tasty, and gorgeous holiday dessert.
Step 1: Acquire ingredients
angelfood cake (made from a box is dandy; purchased if you must)
vanilla pudding (I used Jell-O instant)
frozen fruit (I used cherries, blueberries, and raspberries from Trader Joe's)
liqueur(s) of your choice (I used plum brandy, marsala, and kirschwasser)
whipped cream to top (optional)
Go ahead and bake your angelfood cake and mix up your pudding. I've made angelfood cake from a box and from scratch, and the difference isn't major- here you're combining it with so many other flavors that any such distinction would be lost. Purchased pre-made angelfood cakes will do, but tend to be a bit dry and sometimes taste off. Pound cake may be traditional, but I prefer angelfood because it's lighter, more absorbent, and complements the berries better.
I used a trifle bowl (purchased at Target for $14), but you can use any bowl. Glass is preferable, because then you can see all the pretty layers.
