Notes
- COOKS NOTES:
Oven Temps: Oven temperatures are for conventional, if using fan-forced (convection), reduce the temperature by 20˚C.
Measurements: We use Australian tablespoons and cups: 1 teaspoon = 5 ml, 1 tablespoon = 20 ml & 1 cup = 250 ml.
Herbs: All herbs are fresh (unless specified) and cups are lightly packed.
Vegetables: All vegetables are medium size and peeled, unless specified.
Eggs: We use extra-large size and eggs are 55-60 g each, unless specified. - TUNA
I personally lean towards using tuna in oil as it imparts a richer flavour, in my opinion. However, feel free to use any type of tuna you have available; the sandwich still turns out delicious even with tuna in springwater. It’s worth noting that not all tuna is of the same quality, and usually, the higher the price, the better the quality. I opt for a premium brand like Safcol, but you can use whatever you have or what fits into your budget. - MAYONNAISE
I have a preference for the rich flavour, distinct taste, and smooth texture of whole egg mayonnaise. I find that it enhances the overall creamy profile, particularly in this sandwich. An alternative option is to use Japanese Kewpie mayonnaise. When opting for whole egg mayo, I typically choose Best Foods or S & W brands, readily available at most supermarkets and similar stores. - BREAD
I personally prefer using wholemeal or wholegrain-style bread for this tuna sandwich, but feel free to use ANY type of bread. You can get creative and use crackers like Vita Veet’s, Ryvita’s, or Salada’s as a base. Alternatively, you can opt for wraps, rolls, or even stuff the filling inside sushi rolls for a unique twist. The choice is yours! - STORAGE
I prefer preparing this in advance to allow the flavours to blend, and I particularly enjoy the result of a well-chilled filling. However, the choice is yours; you can also use it immediately after preparation. This recipe yields two substantial sandwiches, but feel free to double or triple it based on your requirements. Once prepared, store the filling in an airtight container in the refrigerator for up to three days.
