Ma-La Oil - cooking recipe

Ingredients

1 cup corn or 1 cup peanut oil
1 cup sesame oil
1/2 cup scallion, thinly sliced
15 pieces fresh ginger, smashed (quarter-size slices)
2 tablespoons szechwan pepper
2 tablespoons red chili pepper flakes
2 teaspoons kosher salt

Preparation

Combine all of the ingredients in a heavy, non-aluminum 1 1/2-quart saucepan.
Rest a deep-fry thermometer on the rim of the pot. Over moderately low heat, bring the mixture to a bubbly 225 degrees F, stirring occasionally.
Let simmer for 15 minutes, checking to ensure the temperature does not rise.
Remove from the heat and let stand until cool or overnight.
Strain the oil without pressing on the solids; then, discard the solids.
Store the oil in an impeccably clean glass jar at cool room temperature.
