Street Tacos with Avocado Jalapeno Crema

Street Tacos
2 lbs. ground beef ( I use 93% lean so I don't have to drain it.)
1 tsp. cumin
1 tsp. chili powder
1 tsp. oregano
1/2 tsp. paprika
1/2 tsp. salt
1 tsp. pepper
corn tortillas
1 medium white onion
1 bunch cilantro
lime wedges

Avocado Jalapeno Crema
1 ripe avocado
1 cup sour cream
1/4 cup hot jalapeno liquid (from a jar of canned jalapenos)
1/4 - 1/3 cup water

       In a blender jar add the avocado, sour cream, jalapeno liquid and 1/4 cup water.  Blend until smooth.  Add more water until it is a thick sauce consistency.  Pour it into a ziploc bag and cut the corner off to add to the tacos.  Set aside.
       Cook the ground beef and add the cumin, chili powder, oregano, paprika, salt, and pepper. 
Dice the white onion and chop the cilantro.  Mix them together in a small bowl.  Over a low flame cook the corn tortillas, just until they begin to brown on the edges, one at a time. (I lay them right on top of the burner to cook.)  Turn the tortilla every 20 seconds for about a minute or two.  Top with ground beef, onion cilantro mix and crema, and then squeeze fresh lime juice across the top.
