Roasted Jalapeno Oil help - recipe or store [moved from Toronto board]

[Jamie Eats Burgers]

Dear Chowhounders,

I frequent Bellwoods Brewery, and I love their duck hearts with roasted jalapeno oil.

There doesn't seem to anything on google about making jalapeno oil.

Can anyone offer their advice on how to make it (preferable) or where to buy it?

Cheers,

Jamie

Roast/grill jalapeno till lightly charred. Leave the seeds in. Chop. Put in olive oil. Let sit.

how long to let them sit? obviously the longer the better, but what is a good ballpark?
