Horseradish Relish

Three ingredients, ten minutes, and a condiment that beats anything jarred. Fresh horseradish root gets grated and combined with white vinegar and salt, sealed in a jar, ready to fire up roast beef sandwiches and prime rib for weeks.

The vinegar does more than preserve. It stabilizes the heat in fresh horseradish, which is famously volatile, building a sharp pungency that mellows over time but stays present. Adding the vinegar quickly after grating locks in that bite. Waiting too long lets it dissipate, leaving you with a flat, watery condiment.

This is a process that earns respect. Open windows before grinding the root, the volatile oils that make it bite will make your eyes water harder than any onion. A blender or food processor is gentler on the cook than a box grater.

The flavor sharpens at first and softens after a week in the fridge. Both stages have their place, fresh and screaming for steak, mellower for adding to a creamy sauce later on.

Variations

• Add 2 tablespoons sour cream or crème fraîche to the finished relish for a creamy horseradish sauce
• Stir in a pinch of sugar or grated beets for a Polish-style chrzan ćwikła with color and gentle sweetness
• Blend with mayonnaise and lemon juice for a sandwich spread to slather on a roast beef bun
