Leek and Caerphilly Tartlet Crostini

This crostini is a sophisticated nod to Welsh flavors, featuring sweet, slow-cooked leeks folded into a creamy, tangy Caerphilly cheese mixture. Baked until golden and bubbly, the rich, savory topping contrasts beautifully with the crisp, toasted baguette slice. The subtle sweetness of the leeks and the sharp, crumbly cheese create a perfectly balanced bite.

Chef's Tip & Pairing

A crisp, dry white wine like a Sauvignon Blanc or a traditional Welsh cider will cut through the richness of the cheese and complement the subtle sweetness of the leeks. To ensure the leeks are clean, slice them first and then soak them in a bowl of cold water, agitating to release any trapped dirt.
