Smooth Peanut Butter-And-Jelly Sandwich

Aesthetic lovers, this recipe is for you: We've recreated the pb & J peanut butter and jelly sandwich that recently took the internet by storm. The gelatinous texture isn't for everyone, but to be honest, it tastes better than expected. White (bread?) the layer resembles a sweetened cream and tastes almost like pan cotta. The jelly layer is slightly sweet and tangy, and the peanut butter layer tastes like a muted version of peanut butter. Agar-agar powder can be found in most specialty or Asian markets. Be careful that the dough does not freeze too much between the layers — otherwise the layers will not connect. However, if you don't wait long enough, the layers will connect and mix. Cooking something so delicious requires skillful timing.
Prepare the bread layers: Whisk together the water and agar-agar in a small saucepan. Place the skillet on medium-high heat and whisk together the milk, sugar, cream and salt. Cook, stirring frequently, until the mixture boils and the sugar is dissolved. Remove from heat and pour half of the mixture into an 8-inch square dish or glass dish. Refrigerate until slightly set, but still warm, about 7 minutes. Leave the remaining bread layer mixture warm.While the bread layer is solidifying, prepare the jelly layer: whisk together the water and agar in a small saucepan.
