Danny G's carmanto bean recipe
INGREDIENTS:
1 can cargamanto beans rinsed and drained
avocado oil in the pan
1⁄4 green pepper chopped
1⁄2 yellow onion diced
2 garlic cloves minced
1 can El Pato hot tomato sauce
1⁄2 tsp. cumin
1⁄2 tsp. paprika
salt & pepper to taste
Heat oil in the pan
Add pepper, onion, garlic
Saute for about 5 minutes until softened
Stir in the beans, El Pato, cumin, paprika
Season with salt and pepper
Add 1 cup water or broth
Bring to a boil then reduce to simmer
Reduce for about 10-15 minutes stirring occasionally to preferred
consistency
Serve over rice with some avocado or sour cream
This is great as is, but carnivores may want to add some meat.
Living in the Polish neighborhood that I do, I first sliced up and browned
some fresh made Kielbasa from the local smokery and put it aside before
softening the veggies in the fond, then adding it back again during the
simmering process. Multicultural chef's kiss. - Danny

Episode 158: Chris Benson of Benson amps and Bryan Sours of Soursound transformers make their long-awaited returns to the Truth About Vintage Amps. Why? They want to tell us all about the logging truck of an amp they are currently building, a 700-watt(!) all-tube beast dubbed Babylon!

The Babylon will feature 14 KT88 tubes, 16 total speakers, three knobs, and two power cords. It's literally the most powerful tube amp they could make without requiring a dryer outlet.
Check our Instagram for a sneak peek at the creation.
