MAT-YEE-SE is obviously, is the phoenetic name of a recipe. I've never met anyone else who was familiar with it, but everybody we introduce it to likes it. I'd like to hear from you if know anything about this recipe.

In our family, this was considered a very traditional Czech dish. We usually ate it at the end of a long family event day. At about 11 pm, someone would suggest a batch of mat-yee-se and eveyone would pile into the kitchen to cook them up.

Simply, they are batter-fried jelly sandwiches, similar to French toast.
First I present the "official" family recipe, then an attempt at a more measured one. In these recipes, "spritz" refers to the little batter fringes that crisp up around the edges of the sandwiches.

2 eggs
flour
milk
salt
white bread
jelly
crisco or crisco oil

Beat eggs, add milk and flour and salt. Keep adding flour and milk until you get a very thin yellowish batter. If the batter is too thick you won't get any spritz.
Make jelly sandwiches, cut into quarters, dip in batter and fry in hot oil. Sprinkle with powdered sugar.

Here's an attempt at a measured recipe, but it is untested. I based it on the proportions for thin batter like Palacinky pancakes. It should be thick enough not to be runny but thin enough to produce those tasty spritz. Mom prepared the batter in a blender.

Beat 2 eggs thoroughly.

Gradually add 2 cup flour and 1/4 tsp. salt.

Slowly pour in up to 2 cups of milk while blending/stirring.

Pour batter into a shallow dish for dipping.

Make sandwiches of white bread and grape jelly, and cut into quarters.

Dip sandwich quarters into batter and fry in medium hot oil, turning once to brown top and bottom. Drain on paper towels and serve sprinkled generously with powdered sugar.
