Welsh Rarebit
Created by Chef Thomas
Sharp cheddar melted into ale with mustard and Worcestershire, spread thick on toast and grilled until the surface blisters, bubbles, and turns the kitchen into the kind of place you never want to leave.
Rain on the window. The heating on for the first time in months. You open the fridge and there's a block of cheddar, half a bottle of ale from the weekend, some bread that needs using. This is a Welsh rarebit evening.
It's cheese on toast, but it isn't. The difference is the sauce: cheddar melted slowly into ale, sharpened with mustard and Worcestershire, spread thickly over good toast and grilled until the top blisters and turns the colour of a bonfire. It puffs slightly. It bubbles. The kitchen fills with a smell so good it borders on unreasonable for something that takes fifteen minutes and costs almost nothing.
I've made this hundreds of times. It's in the notebook more than once, usually with a one-word note beside it: "rain" or "Tuesday" or "needed." It's the meal I make when I want something that feels like someone is looking after me, even when that someone is just me, standing at the counter with a wooden spoon and the grill on. We're only making dinner. But sometimes dinner is the whole point of the evening.
The cheese matters. Use something with real bite, a mature cheddar that crumbles when you cut it and smells of something. A mild block from the supermarket will melt, but it won't say anything. You want cheese that has opinions.
The technique, the tradition, and the story behind every dish.

Instructions
- 1
Toast the bread
Heat your grill to high. Toast the bread on both sides until it has some colour and structure but hasn't gone rigid. You want it firm enough to hold the weight of the sauce without going soggy, but not so dried out that it shatters when you bite into it. Set the slices aside on a baking tray.

Make the roux
Melt the butter in a small saucepan over a medium heat. When it foams, add the flour and stir it in with a wooden spoon. Cook for a minute, stirring constantly, until the paste smells biscuity and has lost its raw, floury smell. Your nose will tell you when it's ready.
Keep the heat steady, not fierce. A roux that catches on the bottom will taste bitter and there is no disguising it in a sauce this simple. - 3
Add the ale
Pour in the ale gradually, stirring as you go. It will spit and seize up for a moment, which is fine. Keep stirring and it will smooth out into a thick, glossy sauce. Let it bubble gently for a minute until it thickens enough to coat the back of the spoon.
Use something you'd drink. A decent bitter or a dark stout both work. Lager won't give you enough flavour. If you've only got white wine, use that, but it becomes a different thing entirely. - 4
Melt the cheese in
Take the pan off the heat. This matters. Stir in the grated cheese, a handful at a time, letting each addition melt into the sauce before adding the next. Then the mustard, the Worcestershire sauce, and a good grinding of black pepper. The sauce should be thick, rich, and deeply savoury, the colour of old gold. Taste it. Adjust. More mustard if you want heat, more Worcestershire if it needs depth.
Cheese melted over direct heat goes grainy and splits. Off the heat, it stays smooth. The residual warmth of the sauce is enough. Trust it. - 5
Add the egg yolk
Beat the egg yolk and stir it into the sauce quickly. It enriches everything and helps the rarebit puff slightly under the grill. Don't linger here. The sauce is warm enough to cook the yolk if you leave it sitting.

Grill until blistered
Spread the cheese sauce thickly over each slice of toast, right to the edges so nothing burns. Place them under the hot grill and watch. Two to three minutes, perhaps four. The surface should blister and bubble, going from golden to deeply bronzed in patches, with dark spots where the sauce has caught. The smell will fill the kitchen: toasted cheese, beer, mustard, something deeply, unavoidably good. Pull them out while the top is still moving, still alive with heat. Eat immediately. This waits for no one.
Chef Tips
- •The cheese is everything. Use a properly mature cheddar with some sharpness to it. Something aged, something that fights back when you taste it. A West Country cheddar or a good Lancashire will do the job. Mild cheddar makes a mild rarebit, and a mild rarebit isn't worth the bread it sits on.
- •Take the pan off the heat before the cheese goes in. I'll say it again because it matters: off the heat. Cheese that meets direct flame goes grainy and oily. The warmth of the sauce is enough to melt it smoothly. Patience costs nothing here.
- •Don't be shy with the sauce. Spread it thick and push it right to the edges of the toast. Exposed bread under a hot grill burns, and burnt crusts are a distraction from something that should be entirely about the cheese.
- •This is good on its own, but it's better with a handful of watercress on the side, dressed with nothing more than a squeeze of lemon. The peppery leaves cut through the richness and give you a reason to pause between bites.
Advance Preparation
- •The cheese sauce can be made several hours ahead and kept covered in the fridge. It sets quite firm as it cools, which makes it easier to spread on toast. Let it come to room temperature for ten minutes before spreading, or spread it cold and let the grill do the work.
- •If you want to prepare a batch for the week, the sauce keeps well in the fridge for three to four days. Spread on toast and grill as needed. This is a good thing to have waiting.
