Ice Cream!

It's summer!  Who here makes her own ice cream in the summer?  I find it to be a fun and interesting project, especially for kids.
The big issues with ice cream making seem to be texture and flavor balance.  Home-made ice cream is invariably "rockier" than store-bought, too much cream in the mix will produce a "slimy" texture, and ice creams with an egg base can become grainy if not "pre-treated" by chilling the custard overnight.
The toughest flavor of ice cream to make is certainly chocolate.  Using actual chocolate in the mix is tricky; it'll get grainy on you or it won't be "chocolatey" enough.  Using cocoa in the mix will "dry" it and you'll get the grainy problem again, compounded by a bitter aftertaste.  I have found that using both produces decent results, but it never seems "chocolatey" enough unless I add shaved chocolate to the end result and then I have the grainy problem again.
