How to make a rainbow-colored grilled cheese sandwich (glitter optional)

In today’s food section, I explained the recent phenomenon of “unicorn food,” a colorful, glittery subset of the highly visual “internet food” movement.

Rainbows, sprinkles, glitter and stars are staples of so-called unicorn food, but that doesn’t mean all the dishes are sweet. This colorful, savory grilled cheese is from Rachel Johnson’s new book, “Unicorn Food: Magical Recipes for Sweets, Eats and Treats.” Contributed by Rachel Johnson

There are no fewer than four cookbooks with the title “Unicorn Food” coming out this year, and one of them is by Austin author Rachel Johnson, the recipe developer behind stupidgoodrachel.com.

In the story, you’ll find recipes for birthday cake pancakes and a turmeric lassi. Some of the unicorn food recipes are more natural than others, but if you’re a cook who doesn’t mind using plain ol’ food coloring to brighten up your day, here’s a tie-dye grilled cheese sandwich that is a treat to look at and — with all those good cheeses — delicious to eat, too.

As if you needed another excuse to use sprinkles for breakfast, these birthday waffles from Jessica Merchant’s “Pretty Dish” are filled with sprinkles and served with ice cream. Contributed by Jessica Merchant

Tie-Dye Grilled Cheese

Don’t freak out, but this is the grilled cheese of your dreams. The multicolored cheese pull is just perfect to generate a like for your Instagram!

— Rachel Johnson

4 ounces shredded mozzarella
4 ounces shredded cheddar
4 ounces shredded Gruyere
Food coloring (pink, green, blue and purple)
4 tablespoons softened butter
8 (1/2-inch) slices white bread (such as sourdough, pullman or brioche)
Kosher salt, to taste
Edible glitter (optional)

Mix the cheeses together in a large bowl. Divide between four bowls and tint each cheese with each food coloring by stirring around with a spoon (about 2 drops per color per bowl will do).

Heat a nonstick pan or griddle to medium-high heat. Spread the butter evenly on one side of each bread slice.

Place four slices of bread, butter side down, on the heat surface. Top with each color of cheese in any preferred pattern. Sandwich with another slice of bread, butter side up. Cook on the griddle for 2 to 3 minutes or until the cheese is starting to melt. Flip and cook another 2 minutes, or until the bread is toasty and golden. Sprinkle with salt and edible glitter in case you are extra. Makes 2 sandwiches.
