Wha!? (hic) Actually, I've tried making jams with booze and frankly, I don't care for them. If
the alcohol is at all present, I find the flavor overwhelming and if you use any of the fruit flavors, you'd be far better off using the actual fruit for both flavor and gel-set effect. Why use Cointreau when you get a better flavor with orange zest? Same-same with kirsch. But that's just me. I prefer my preserves and my liquor separate . . . but in enormous proportion.
