Preparation & Mise en Place
To ensure your Tuna Sweetcorn Sandwich hits professional standards, keep these tips in mind:
- The Double-Drain Technique: Drain your tuna in a sieve and then press it with a fork. This ensures your Tuna Sweetcorn Sandwich filling stays thick and creamy rather than watery.
- The Citrus Lift: Always add a teaspoon of fresh lemon juice. The acidity cuts through the richness of the mayonnaise and highlights the sweetness of the corn.
- Structural Layering: If adding cucumber, slice it paper-thin. This adds crunch without making the Tuna Sweetcorn Sandwich difficult to eat.
- The Butter Barrier: Apply a thin, even layer of softened butter to the bread. This creates a moisture-proof seal, keeping the bread soft and fresh for hours.
Traditional Global Tuna Sweetcorn Sandwich Recipe
Serves: 2
Preparation Time: 20 minutes
Flavour Profile: Creamy, lightly sweet, savoury, and comforting
Ingredients
- 1 can (160 g drained) tuna in water or oil
- ½ cup sweetcorn kernels, drained
- 3 tablespoons mayonnaise
- 1 teaspoon lemon juice
- Salt, to taste
- Freshly ground black pepper, to taste
- 4 slices soft white or whole wheat bread
- Butter, softened (optional)
- Lettuce leaves or cucumber slices (optional)
Instructions
- Prepare the tuna:

- Make the filling:
- Add sweetcorn to the tuna, followed by mayonnaise and lemon juice. Mix gently until well combined. Season with salt and black pepper according to taste.
- Prepare the bread:
- Lay the bread slices flat on a clean surface. Lightly butter one side of each slice if desired, which helps prevent the filling from soaking into the bread.
- Assemble the sandwich:
- Spread the tuna sweetcorn mixture evenly over two slices of bread. Add lettuce or cucumber if using, then top with the remaining bread slices.
- Finish and serve:
- Press gently, cut in half, and serve immediately for the best texture and flavour.
