Over the long holiday weekend I made some grilled catfish that was a home run with all:
1 bottle of Apfelwein
Covered the fillets in apfelwein, soaked for 30 minutes in a tupperware containter. Poured off the majority of the liquid, leaving just a little bit in the bottom of the container. Threw in a number of lightly crushed sprigs of dill, squeezed the lime juice then sliced the lime and tossed that in. Let this sit for another 15-20 minutes then on to the grill. Grilled both sides until cooked through out. The fillets came off the grill with tons of great flavor and were super moist.
