They're pretty good. They have a lot more texture than most pops because they're whole fruit rather than juice, and I like the texture a lot, but the mixture separated in the freezer, so the tip of the pop tastes sweet and alcoholic, but the rest of it is milder and has more chunks. I don't know how to keep it from separating, since I think it happens in the freezer before it freezes. Something I would tweak the next time is to add pineapple juice. I think the intense sweet-acid taste would be great with the cucumber and melon. I would probably leave out the alcohol as well. It definitely made a difference, but I don't know if the effect was better than it would have been without the alcohol. I could, however, see this going in the frozen cocktail direction with tequila or gin in place of the liqueur. Anyway, here's the recipe as I made it.
2 cups cubed green melon
1 cup cubed cucumber
2 tbsp sugar
1/4 cup Tyku liqueur
Blend melon and cucumber together. Add sugar and liqueur. Pour into popsicle molds and freeze.
