I grew up with shortcake being the one on the side of the Bisquick box. Never saw a reason to change it. Yes, lightly smash the berries with sugar and let sit overnight. Pile them on the square of shortcake and, it gets strange here, pour some 1/2 and 1/2 around it. Finish it off with a big old squirt of spray whipped cream. We make an entire meal of this several times in the peak of berry season. I've made it with blueberries, raspberries and blackberries but all seem like imitations next to the real thing. If no one is watching me, I often split the shortcake and butter it and zap it in the microwave just to melt the butter. When it come to this stuff, more it better. And much more, is much better.
