What Have You Done To My Kaya Toast?

Updated: Aug 1, 2020

For years, I had been experimenting with different types of methods and ways to craft out the best kaya toast. I can finally say that this is probably the best version. Probably. Kaya toast has been a staple in Singapore's brunch; it is the Singaporean's peanut butter and jelly sandwich. Kaya + butter were spread on thin slices of toasted bread and enjoyed over a cup of coffee.

I made that kaya sandwich in 2015 using a panini press. I even drizzled some gula melaka syrup over the top for good measure. I still wasn't satisfied tho.

In 2018, I made this kaya toast with pandan caviar. That was the very 1st time I had toyed around with molecular gastronomy and I failed epically. I allowed the "caviar" to cool before dripping into the cold oil, hence the awkward shapes.

Fast forward 2020, this is the vision I finally settled on. I drew inspirations from Sqirl, Los Angeles and Chef Studio. If you have not check out Sqirl yet, please do so. Their jam and toast are simply the best despite recent allegations. Also, check out Chef Studio YouTube channel for lots of brilliant chefy recipes.

You get the crispy-mayo-toasted bottom, soft bite with light, fluffy, buttery, savory, dense and sweet topping; the coffee caviar cut thru' all that richness perfectly with an amazing aftertaste. Every mouthful is loaded with different types of textures as well. This is indeed a flavor bomb. I am literally drooling thinking about this. You have to give this recipe a try!
