Orange Mustard Glaze

Credit to FoodNetwork's Guy Fieri (Diners, Drive-ins & Dives) who visited Crazee Burger in San Diego where they serve a turkey burger with an orange-mustard glaze. There's a recipe available from Guy...maybe, maybe not (???) the exact recipe from the restaurant. I made my own version of an orange-mustard glaze for a twist on the typical burger (or over beef, chicken, etc)...mine was a turkey burger with Swiss cheese and crispy shallots. Most of the same ingredients in my sauce version, but a little more mustard and a little less heat (I'm a wimp with spicy stuff!).

Ingredients
1 T vegetable oil
¼ C finely diced onion
2 T diced jalapeno pepper (I left the seeds out, but if you like heat, leave 'em!)
1 clove garlic, minced
½ C orange marmalade - with the peel adds nice texture
2 T grainy dijon mustard
pinch each black pepper and chili powder

Directions
Cook onion in a small saucepan with vegetable oil until translucent; add jalapeno and garlic, cooking until softened. Add remaining ingredients; bring just to boiling, stirring to combine evenly.
