KitchenAid juicer attachment
Fresh squeezed juice is incomparable--the Feds may be trying to keep us safe with pasteurization but we think most of the flavor dies along with the critters. If you have a KitchenAid stand mixer, consider picking up the juicer attachment [$25.95]. It makes quick work out of a bag of citrus. We juiced local organic grapefruit mixed with local tangerines this afternoon with great results. The juice is great as is, mixed into a cocktail or even as a base for salad dressings. It would also make a great base for sorbet, but that's for another day.
If you get the KitchenAid attachment, do what we did and dump the built-in pulp/seed screen. Just juice into the bowl through a fine mesh strainer. It's much larger which means you don't have to keep stopping to clean out the goop.
