"Green Broth" in Portuguese. As seen on the deli.
Any greens (we try and use kale from Sale, but whatever is in season),
2 large onions (chopped),
1 kg potatoes (peeled & diced),
salt & pepper.
Blanch greens (immerse in boiling water) for 1 minute to get rid of bitterness.
Sweat onions & garlic, then add the potatoes and cover with stock. Boil until soft.
Add greens, blend, and season with salt & pepper plus a glug of olive oil and a sprinkling of smoked paprika to garnish.
