Tuna in Blackberry Sauce

two quarter pound tuna steaks, frozen, thawed
1/3 large white onion, diced
5 cloves garlic, minced
3-4 oz sherry (not cooking sherry, but decent sherry or amontillado you might drink)
1T turmeric
pinch allspice
pinch cinnamon
3 drops of Brother Bru-Bru's hot sauce
1/2 C vegetable broth
1C cooked blackberry puree
1T tapoica starch moistened in a little vegetable broth

soften onion, garlic in a little oil. Add sherry and spices. When the aroma of alcohol is gone from the sherry, add the tuna, turning often. When the tuna is about half cooked through, add blackberries, vegetable broth, and stir in hot sauce.

(If you don't have blackberry puree, just put a little water in a pan, and add a mounded cup of blackberries, heat, and mash with a potato masher. You'll get about a cup.)

When the tuna is done to your taste (rare tuna is fine, but don't let it get TOO dry!), remove it to the serving dish. Take the tapioca starch mixture, and add it to the sauce. When the sauce is thickened, smother the tuna with the sauce, and serve.
