Steaming the lobsters yields better flavor, however, boiling will also work:
Clean and crack lobsters, removing meat and slicing into bite-size pieces. In deep bowl, squeeze limes, lemon, and satsumas over mint leaves and sugar. Muddle together for three to four minutes to release mint oil. Mix in lobster, blueberries, bell pepper, cilantro, and sambal. Season with salt and pepper.
To serve: Divide lobster mixture into martini glasses, and garnish with lime zest. Immediately before serving, pour one to two ounces of Champagne in each glass. Serve with plantain chips.
Place all ingredients in a pot of boiling water. Boil lobsters for about 12 to 15 minutes, then immediately place in ice water bath for three to four minutes to stop cooking.
