Understanding Aioli and Horseradish Magic

Aioli traditionally refers to a garlic-infused emulsion from Provence, but modern versions embrace mayonnaise as a base for speed and creaminess. Horseradish, a root vegetable from the Brassicaceae family, provides sinus-clearing pungency due to allyl isothiocyanate compounds, making it a staple in sauces for roast beef and seafood. Prepared horseradish is grated and preserved in vinegar, offering convenience without grating fresh roots.

The beauty lies in balance: creamy mayo tempers the spice, lemon adds brightness, and garlic brings depth. Variations allow personalization—roast garlic for mellow sweetness or add Dijon for mustardy edge.

This foundational recipe yields about 1 cup, ready in 5 minutes with pantry staples. It’s the perfect starting point for beginners.

• 1 clove garlic, finely minced or grated
• 1 teaspoon fresh lemon juice
