Citrus and Fennel Rub

Ingredients

Equipment Needed

• •Small dry skillet
• •Mortar and pestle (or heavy pan for crushing)
• •Microplane zester
• •Small mixing bowl

Instructions

1. 1

   Toast the fennel seeds

   Set a small dry skillet over medium heat. Add the fennel seeds and toast, shaking the pan occasionally, until fragrant and slightly darker, about two minutes. You will smell anise rising from the pan. Remove from heat immediately. Fennel burns quickly once it decides to go.

   Listen for the seeds to start crackling. That is your signal they are nearly done.
2. 2

   Crush the seeds

   Transfer warm seeds to a mortar and pestle. Crush them coarsely, leaving some texture. You want pieces, not powder. The irregular bits will catch on the meat and bloom in the heat. If you do not have a mortar, press firmly with the bottom of a heavy pan.

3. 3

   Zest the citrus

   Use a microplane to remove only the bright outer layer of the oranges and lemon. Stop before you reach white pith, which tastes bitter. The oils should perfume your hands. If your citrus does not smell alive when you zest it, find better fruit.

   Organic citrus matters here. Conventional fruit is often waxed, and the zest goes directly into your food.
4. 4

   Combine everything

   In a small bowl, combine the crushed fennel seeds with orange zest, lemon zest, sea salt, black pepper, and red pepper flakes. Add the garlic paste and thyme leaves. Work the mixture together with your fingers, pressing and rubbing until the oils release and everything becomes fragrant and slightly moist.

5. 5

   Use or store

   The rub is best used within a few hours while the citrus oils are still vibrant. For pork, massage it into the meat and let it rest at least one hour, or overnight in the refrigerator. For fish, apply just before cooking. The rub should wake up the protein, not dominate it.

Chef Tips

• •Buy citrus from farmers when you can. Supermarket fruit is picked weeks early and stored cold. Farmers market oranges were on the tree days ago, and the zest knows the difference.
• •This rub pairs beautifully with pork shoulder, pork chops, or firm white fish like sea bass or halibut. For chicken, add a bit more lemon zest to brighten the flavor.
• •If making ahead, store the rub without the garlic, then add freshly minced garlic just before using. Garlic loses its punch quickly once exposed to salt.
• •In summer, when citrus is tired, try this same approach with stone fruit. A peach and fennel rub on grilled pork is worth remembering.

Advance Preparation

• •The rub without garlic keeps in an airtight jar for up to one week refrigerated. The citrus oils will fade but remain usable.
• •For the brightest flavor, make the rub the day you plan to use it. The citrus oils are most alive in those first few hours.
• •Rubbed pork can rest overnight in the refrigerator, improving both flavor and texture. Fish should be rubbed just before it meets heat.
