ok... here are the results from two different approaches:
first i marinated a salmon steak in equal parts soy sauce and maple syrup combined with 2 T of dark rum for 3 hours.
in the non-stick skillet, i did a quick sear with a mixture of butter and olive oil and thru it in the oven to continue cooking. after 5 min in the oven, i removed it and applied the maple butter and then, put it back in the oven (it was off) for about a min.
result: OK, but nothing to talk about.
2nd approach. i marinated 3 tilapia fillets in 2 T soy sauce & 2 T maple syrup, fresh ground ginger, and in the juice of 1 ripe mango with a few mango pieces (about half the mango) thrown-in for good measure.
again, i let them marinate for 3 hours and pan fried them until all the way cooked. then, i removed them to a plate, and poured the marinade (including the mango pieces) in the skillet, dumped-in about 2 T lurpak butter and cooked it down until thick... then, added-in the fillets to warm them up.
result: i'm giving myself 4 stars out of 5... this was delicious.
i need more experimentation with the maple butter...
