Welsh rarebit with leeks on sourdough

Butter, leeks, mature cheddar, Worcestershire sauce, egg yolks (no), Dijon mustard, cayenne pepper, Red Hill Brewery Golden Ale (used some random Belgian ale instead), sourdough bread.

Verdict: nice but nothing spesh. Don't think I'd bother again with the leeky chopping/cooking (not that it's onerous, just that I'm awfully lazy and the extra taste doesn't seem to justify the effort) for what is essentially a toasted cheese sandwich – and I love a toasted cheese sandwich, don't get me wrong. I would consider doing something similar – i.e. making a paste with grated cheese and beer and spicy things – sans leeks.
