Sweet Whiskey Salsa Marinade

Tonight, Geoff and I decided to have Salmon, but we wanted something different with it.  Geoff began thought of adding diced tomato and brown sugar to make it similar to BBQ sauce.  I said, why not add a Poblano pepper, diced onion, and a diced tomatillo.  Right before we were done I was feelin' lucky, so I said, let's add whiskey.  It turned out delicious, so here it is...

2 tsp oil (we used grapeseed, but olive would work too)
1 Tbsp butter
2 tsp brown sugar
1 diced pepper (poblano, habanero, chili or jalapeno will work)
1/3 cup diced fresh onion
1/2 cup diced fresh tomato
1 medium, diced tomatillo
1-2 Tbsp whiskey

Start with the oil and butter in a hot pan, add your brown sugar, onion and pepper.  Allow it to reduced down until just before the onions start to brown/carmelize (but make sure they are soft).  Then add your tomato, and tomatillo with their juice.  Allow to cook down a bit more before adding the whiskey, you don't want it to get too runny.

Salt to taste, and use over fish, shrimp, chicken or just rice.
