6 jumbo tiger prawns
1 cup flour

Salt and pepper to taste
1/4 cup Dos XX Mexican beer
Canola oil (enough oil to deep fry)

Heat a large wok or deep fryer with canola oil.

Mix flour, chili powder, salt and pepper, and beer to make batter. Batter should be thick enough to stick to shrimp. Dip shrimp in batter. Deep fry until crisp.
