Brunch Week

It is time for #BrunchWeek again! This year’s event is featuring a variety of sweet and savory recipes perfect for brunch.

Due to our current cross-country move, I was only able to participate on Monday (Korvapuustit/Finnish Cinnamon Rolls) and today, but check out the rest of the bloggers for even more of brunch-themed recipes from the past week.

Japanese Coffee Jelly

For the final #BrunchWeek day of 2022, I am sharing a recipe for Japanese Coffee Jelly (コーヒーゼリー, Kohi Zeri)!

I first came across coffee jelly here in Torrance, California and it quickly became a favorite. It also doesn’t take too much effort to make at home with only four ingredients and some time to set in the refrigerator.

Instant coffee, sugar, powdered kanten, and water are simmered on the stove until all the powder has dissolved, then transferred to glasses before placing in the refrigerator for at least 4 hours to overnight.

Once set, the kanten creates a firm, jello-like texture and will last covered in the refrigerator for up to 2 to 3 days for an easy make-ahead dessert.

Coffee Jelly Serving Ideas

Japanese Coffee Jelly can be served in a variety of ways. A few favorites include topping with sweet cream or half and half, whipped cream, or even ice cream for something a little more decadent.

After preparing the mixture, it can be divided among individual serving glasses or even an 8×8 inch (20×20 centimeter) baking dish if you want to cut the jelly into bite-sized cubes.

Smaller cubes are a great addition to drinks such as milk for added texture.

I sometimes adjust the amount of sugar in the jelly depending on how I will be serving it. If pairing with something also sweet such as ice cream, I generally add 3 tablespoons (42 grams).

When enjoying on its own or with unsweetened whipped cream or milk, I usually bump the amount up to 4 tablespoons (50 grams).

Notable Ingredients

To set the coffee, I used powdered kanten. Kanten (寒天) is a vegan thickener derived from an edible red algae (テングサ, Tengusa) and creates a more firm texture compared to animal-based gelatin. It comes in different forms, but the powder is the easiest to work with.

For those in the Los Angeles area, I have been able to find kanten in Mitsuwa Marketplace and Tokyo Central.

Gelatin

If you are unable to find powdered kanten, this recipe can also be made with powdered gelatin. The way you prepare it will change just a bit and the resulting texture will be a little more wobbly.

Instead of adding straight to the pot, place 2 tablespoons (30 milliliters) water in a small bowl and sprinkle 1 tablespoon (9 grams) gelatin powder evenly over the top. Allow to sit at room temperature for 10 minutes.

Simmer the 2 cups (470 milliliters) water, sugar, and instant coffee in a small pot until smooth. Remove from heat and whisk in the soaked gelatin until dissolved. If it does not dissolve completely, place back over very low heat briefly. Do not boil the gelatin (only the kanten).
