How to make homemade RKT

You can watch this video below for a homemade RKT recipe. You will also find all the steps on this post in case you need further detailed information.

Step-by-step RKT recipe

You just need 4 main ingredients to make it:

25gr butter
450gr marshmallow
500gr Rice Krispy cereal
Release agent spray

Which brand of rice and marshmallows can I use?

I’ve tried different brands of rice and marshmallows and after a lot of testing, I’ve concluded that a specific brand is not relevant for making a perfect RKT recipe. To elaborate modeling chocolate, for example, the brand it’s, in fact, important, but not in today’s recipe. When you choose your brand for rice and marshmallows, I recommend using:

High porosity, short grained rice.
Compact, firm marshmallows, not very spongy.

A really fine rice will allow the mass to be lighter and less grainy. Melted marshmallows must be quite rigid, that’s why they don’t have to be spongy.

What do I need to make the recipe?

A big bowl
A silicone spatula
A microwave or a frying pan
A greased working surface
Plastic wrap
Refrigerator (optional)

How to elaborate RKT

Put the butter in the bowl and melt it in the microwave.
Spread the butter all over the bowl, pour the marshmallows in it and microwave them for 2 minutes. After that, grease a silicone spatula and stir until you get a spongy, homogeneous mass. If you want the RKT to have a toasted flavour, melt the butter in a frying pan and add the marshmallows in the same pan (as a microwave substitute).
Pour 2/3 of the rice into the bowl and integrate with a well greased spatula to prevent sticking. Once integrated, pour the rest of the rice and repeat the process.
When you’re not able to remove it with the spatula anymore, grease a smooth surface and put the mix on it. Grease your own hands and knead until the mass becomes a solid block.
Wrap it with plastic and let it rest for a few hours. In summer, it’s better to put it in the fridge.

Common mistakes

It’s almost impossible to make any mistakes whilst elaborating this recipe, as it is really easy. After having elaborated a giant amount of RKT in my studio or with my students, I noted that the biggest problem you may have is the mass sticking everywhere. If this happens to you, the best solution is to properly grease whatever the mass will be in contact with. If you see that the mass is really sticky, you better wash your hands as well as the working surface, and regrease.
