Preheat the oven to 175°C (top and bottom heat). Grease a heart-shaped baking tin with butter and dust lightly with flour.
Roll the first can of croissant dough open lengthwise and cut it vertically into two equal pieces.
Mix the egg yolk, tomato paste and grated cheese until smooth. If it is too thick, add a little egg white.
Brush the top of one half of the dough with one half of the mixture and place the other half on top. Press gently.
Cut the dough into two wide strips. Cut each end into three strips, but leave the top attached so you can braid it. Make nice braids.
Place the first braid in the shape of a half heart shape in your greased baking pan (or make a round shape). Repeat with the second braid for the other side. Place the slices of cheese on top.
Repeat everything with the second can of croissant dough and the rest of the mixture: fill, braid and place on top of the first layer.
Beat a little egg yolk with a dash of water or milk and lightly brush the top. Grate some extra Emmental cheese over the top.
Bake 20 to 25 minutes in the preheated oven until golden brown and cooked through.
Let it cool for a few minutes on a wire rack, but serve it preferably lukewarm with a spicy drizzle of hot honey.
Tips
- Finish it off with a slice of ham or an extra slice of cheese when serving, for some extra filling.
- No heart shape? Feel free to use a round or square baking tin, that's just as delicious.
- You can steep your hot honey a day in advance to intensify the flavours even more.
- You can also serve this at brunch, with a cup of coffee instead of bubbles.
- Want it less spicy? Skip the chili and just use honey.
