Toum

Toum breaks when oil is added too quickly. The emulsion depends on the crushed garlic holding the oil in tiny droplets — if you pour too fast, the droplets merge and the sauce separates. Always add oil in a stream no wider than a toothpick. Other common causes: warm ingredients (use garlic and oil at cool room temperature), too little garlic relative to oil, or a blender instead of a food processor. If it breaks, add one ice cube and keep processing — the cold sometimes brings the emulsion back.

Keep homemade toum in an airtight glass jar in the fridge and use it within 4 days. Toum is raw garlic under oil, and that mix can grow botulism bacteria at room temperature, so the jar never sits out on the counter: take out what you need with a clean spoon and put it straight back. Throw away any toum that has been out for more than 2 hours. The sauce thickens and mellows over the first 24 hours. Whatever you won't eat in 4 days, freeze on the day you make it: portion into ice cube trays, freeze solid, then transfer to a bag. Thaw in the fridge overnight and whisk vigorously. The emulsion can loosen after thawing, so the texture may be slightly less fluffy, but the flavor stays good.

A food processor is the best tool because its wide bowl gives the emulsion room to form. A high-speed blender can work if you use the tamper to keep pushing garlic down, but it overheats faster and may break the emulsion. A hand mixer does not generate enough shear force for a stable emulsion. An immersion blender in a tall narrow jar works surprisingly well — keep it at the bottom and drizzle oil in slowly. The key with any tool is the slow oil addition, not the specific device.

Traditional toum and traditional aioli are cousins, not twins. Toum is Lebanese, made with garlic, lemon juice, and oil — no eggs. Aioli comes from the western Mediterranean and in its traditional form is just garlic pounded with olive oil; versions with egg yolk, and the garlic mayonnaise most restaurants serve, came later. Toum is fully vegan and dairy-free. The texture of properly made toum is lighter and fluffier than aioli, almost like whipped cream, because the garlic itself acts as the emulsifier.

Fresh toum has a sharp garlic bite that mellows significantly after 12–24 hours in the fridge. For a milder sauce right away, blanch the peeled garlic cloves in boiling water for 30 seconds, then shock in ice water before processing. This tames the harsh allicin without cooking the garlic. Another trick is to remove the green germ from the center of each clove — it carries most of the bitterness. Adding an extra squeeze of lemon juice at the end also balances the heat.
