A British BLT
Back bacon crisped in a hot pan, a ripe tomato that actually tastes of something, crisp lettuce and real butter on proper toast. A sandwich that earns its place in the notebook.

Tuna Mayonnaise and Sweetcorn Sandwich
Created by Chef Thomas
Tinned tuna, good mayo, and a scattering of sweetcorn on buttered bread. The honest sandwich that has quietly fed more people in this country than anything with a menu price next to it.

Atin of tuna. A jar of mayo. Some sweetcorn from another tin. Bread, butter, five minutes. This is not a recipe that needs an introduction, and it knows it.
But I'll say this: the sweetcorn matters more than you think. Without it, you have tuna mayo, which is fine, perfectly decent, nobody would send it back. With it, you have something that works on another level entirely. Each kernel pops between your teeth, sweet and firm against the soft, savoury tuna, and it turns what could be monotonous into something you actually want to keep eating. It's a textural trick, and it's the reason this version became the standard in sandwich shops and school lunchboxes across the country.
I make this when the fridge is bare and the cupboard isn't. A Wednesday evening when you've come in late and there's nothing planned. The tin is already in the cupboard. The bread is on the side. We're only making dinner. Or lunch. Or something to wrap in paper and eat on a bench if the weather's holding. A recipe is a conversation, not a contract, and this one barely needs more than a nod.
I wrote it down in the notebook once, though I'm not sure why. "Tuna. Sweetcorn. Good mayo. Ate it over the sink." That's the whole entry. It didn't need more.
The technique, the tradition, and the story behind every dish.

Mix the tuna filling
Tip the drained tuna into a bowl and break it up with a fork. You're not making a paste. You want it loosened, with some texture left. Add the mayonnaise, a generous spoonful at a time, and the sweetcorn. Stir it through until everything is just combined, the corn sitting in pockets through the tuna. Squeeze in a little lemon juice, then season with salt and pepper. Taste it. If it needs more mayo, add more mayo. If it needs more lemon, you'll know. Trust yourself here.
Drain the tuna properly. Tip the tin upside down and press the lid against the fish to squeeze out as much liquid as you can. Watery tuna makes a sad sandwich. - 2
Butter the bread
Butter every slice, right to the edges. This isn't optional and it isn't about flavour alone. The butter seals the bread so the filling doesn't soak through and turn it soggy by lunchtime. Use real butter, soft enough to spread without tearing. If the bread fights you, the butter is too cold.

Build and cut
Spoon the tuna mixture onto two slices, spreading it generously to the edges. If you're using lettuce, lay it over the tuna now. It gives a cool crunch that earns its place. Press the top slices down gently, cut corner to corner, and wrap in greaseproof paper if it's going somewhere. If it's staying here, put it on a plate and eat it standing at the counter. Nobody will judge you.
Chef Tips
- •The mayo makes or breaks this. Use a good one from a jar, something with a proper egg-yolk richness, or make your own if you have the inclination. Cheap mayo tastes of vinegar and air, and it pulls the whole thing down.
- •Tuna in spring water is lighter. Tuna in olive oil has more flavour and needs less mayo. Either works. If you use oil-packed, drain it well but don't wring it dry. A little oil in the mix is no bad thing.
- •A squeeze of lemon lifts everything. Not half a lemon, just a brief squeeze. It cuts the richness of the mayo and brings the tuna into focus. If you haven't got a lemon, a splash of white wine vinegar does the same job quietly.
- •If you're making this the night before, keep the lettuce separate and add it in the morning. Wet lettuce in a wrapped sandwich is a disappointment nobody deserves.
Advance Preparation
- •The tuna and sweetcorn filling can be made a day ahead and kept in a covered bowl in the fridge. It actually improves a little as the flavours settle.
- •Assemble the sandwich the morning you need it if taking it somewhere. Butter the bread properly, and the filling won't soak through for several hours.
