simple, powerful, and can be added to any recipe (except desserts) to 
spice it up. Note: This recipe requires advance preparation.

Ingredients

1 cup fresh or dried malagueta chiles, or substitute tabascos or 
piquins, stems removed, left whole
1 wine bottle (750 ml.), washed in boiling water and dried, with cork
1 cup vinegar
Olive oil to fill bottle

Instructions

Place the chiles in the wine bottle, add the vinegar and olive oil, and 
stopper the bottle securely. Place the bottle in the refrigerator and 
let the chiles steep for at least 2 weeks, shaking the bottle whenever 
you think about it. Shake well before using.
