This is an easy soup course or palate-cleanser. The flecks of green against the orange make for a lovely presentation.
1 medium cantaloupe, seeded, rind removed, and cut into chunks
1 cup seltzer
1 Tbs. lemon juice
1-2 jalapenos, seeded and finely diced (you may want to wear a plastic bag or latex glove over the hand that will come in contact with the pepper)
In a blender or food processor, combine cantaloupe, seltzer, and lemon juice. Puree, then transfer to serving bowl or individual bowls. Sprinkle with the diced jalapeno.
