Bánh mì bơ

Bánh Mì Bơ is one of the simplest yet most delicious remnants of French colonial heritage. 'Bơ' means butter (or avocado, but here it's butter). While bread and butter is a staple in the West, in Vietnam, local mayonnaise-butter mixtures and fresh vegetables make it exotic. Often sold by street vendors as a 'student snack', combining rich butter with sugar or savoury toppings. This version is a savoury, refreshing variant.

Instructions

1

Mix the soft butter with a pinch of salt and the chopped green parts of the spring onion.

Tip: This 'onion butter' is the base. The fat helps extract onion flavour compounds.
2

Cut baguettes in half and toast in oven or dry pan until cut surface is golden brown and crisp.

Tip: Toasting (Maillard reaction) adds flavour, and the harder surface doesn't get soggy from butter immediately.
3

Mix mayonnaise with lime juice. This 'lime aioli' brings freshness to the fatty base.

Tip: Diluting emulsion (mayonnaise) with acid (lime) makes the sauce lighter.
4

Spread one half of hot baguette with onion butter (let it melt in a bit), the other with lime mayonnaise.

Tip: Melting butter soaks into bread pores.
5

Fill with thin strips of carrot, cucumber, and plenty of coriander.

Tip: Crunchiness of vegetables contrasts with soft, buttery interior.

Recipe FAQ

What butter should I use?
High quality, high fat (82%) tea butter is best. Many use margarine for spreadability, but the taste experience is real with butter.
