Boil carrots whole until almost done but not mushy.
Crush the garlic, oregano, cumin and paprika in a mortar into a paste. I didn't use as much of the seasonings as the recipe called for because we are wimpy here; feel free to add more if you like. They used a whole tablespoon of oregano and more cumin too.
When carrots are cool, cut into discs.
Mix the vinegar and garlic paste together; add water; submerge carrots overnight; salt them.
