Fermented Chili Crisp & Scallion Garlic Confit Oil - A Low-Temperature Confit Method for Flavor and Cannabinoid Preservation

This condiment is a complete preparation on its own. It is a finishing oil where garlic is cooked slowly in fat until sweet and creamy, scallions are preserved bright, and fermented chili provides heat, acidity, and texture.

The Educational Foundation: Why Low-Temperature Confit Works

Confit is not frying. It is poaching in fat at 200°F to 225°F.

At this temperature range, three critical chemical events occur without creating bitterness. First, pectin in garlic and shallots hydrolyzes, turning firm cloves soft and spreadable. Second, Maillard browning is avoided, which begins rapidly above 280°F, so sweetness is preserved. Third, water is gently driven off the surface of the fresh vegetables, which lowers water activity and improves stability while still requiring refrigeration.

For cannabinoid applications, this temperature control is essential. THC has a boiling point near 315°F but begins to degrade into CBN, a more sedative and less desirable cannabinoid for this flavor profile, when held above 245°F for extended periods. Terpenes, which contribute aroma, are even more volatile and evaporate above 150°F-180°F. By completing all high-heat work first, cooling the oil to 180°F, and only then adding a fully decarboxylated and homogenized cannabinoid input, you protect both potency and flavor.

Ingredients - Exact Weights for Consistency:

480ml / 2 cups neutral oil - rice bran or refined grapeseed, both have neutral flavor and high smoke points

70g / 1/2 cup whole garlic cloves, peeled

40g / 1/3 cup shallots, thinly sliced

25g / 1 cup scallions, white and light green only, cut on bias into 1/2-inch pieces

30g / 3 tbsp fermented chili paste - Calabrian chili or fermented gochugaru jang

10g / 2 tbsp dried chili flake - Er Jing Tiao for red color or Aleppo for fruity heat

8g / 1 tbsp fermented black beans, rinsed and lightly crushed to release glutamates

5g / 1 tsp smoked sea salt

4g / 1 tsp granulated sugar

1.2g / 1/2 tsp white pepper

Equipment:

Heavy-bottomed 2-quart saucepan, instant-read digital thermometer, sterilized 16oz glass jar.

Detailed Method:

Cold-start the confit. Combine oil, garlic, and shallots while oil is still cold. Heat slowly to 200°F over medium-low. Hold at 200°F to 215°F for 28-32 minutes. The oil should show lazy bubbles, not a vigorous fry. Garlic is done when a paring knife passes through with no resistance.

Add scallions. Hold 3 minutes more at 200°F. This sets the chlorophyll and keeps the green color.

Remove from heat and cool to 180°F. This cooling window is critical. Use a thermometer - approximately 8-10 minutes.

Bloom fermented aromatics. At exactly 180°F, add chili paste, chili flakes, black beans, salt, sugar, and white pepper. Stir 60 seconds continuously. The residual heat blooms capsaicin for heat and capsanthin for red color without burning fermented sugars.

Optional adult infusion integration. If producing an infused version where legal for adults 21+, add your separately decarboxylated, lab-tested concentrate or infused oil at this 180°F stage. Whisk for 2 full minutes for complete homogenization. Homogenization ensures each teaspoon contains a similar amount. Do not reheat above 200°F after this step.

Cool fully to room temperature, then jar with all solids.

Decarboxylation and Dosing Education:

Raw cannabis contains THCA, which is non-intoxicating. Heat removes a carboxyl group as CO2, converting THCA to delta-9-THC. A common reference protocol is 240°F for 30-40 minutes for flower. The theoretical conversion factor is THCA percentage multiplied by 0.877 to estimate potential THC.

Total potency calculation: (grams of input x THC percentage x 1000 x 0.877) = total milligrams in batch. Divide total milligrams by total teaspoons in batch (this recipe yields approximately 96 teaspoons) to estimate per-teaspoon amount. Effects from ingestion are delayed 60 to 120 minutes and last significantly longer than inhalation. Always start with a very small amount.

Storage, Food Safety, and Legal Compliance:

This recipe contains fresh garlic and scallions in oil, which creates an anaerobic environment. It must be refrigerated at or below 38°F, never stored at room temperature, and discarded after 21 days. Do not water-bath can. For adult use only where cannabis is legal. Keep clearly labeled, dated, and out of reach of children and pets.

How to Use:

Use as a finishing condiment, not a cooking oil. One teaspoon over steamed jasmine rice, congee, soft scrambled eggs, roasted eggplant, or hummus. The garlic cloves are meant to be eaten whole.
