Well, my newbie mistakes were TOO MUCH PEANUT BUTTER and TOO MANY SMOKED ALMONDS. I just love peanut butter and it's ok if I have a spoonful, but not a quarter-jar... hehe.

About the SF jelly/jello and cream thing - it hasn't caused me any problems. I have it a couple of times a week but I don't used sweetened cream, I just buy ordinary full-fat cream - either the thick dollopy type or the whipping type and whip it myself. YUM.
