Slightly more than a spoonful of the attached spoon
Dissolve food colouring in one teaspoon of water. Line parchment sheet in a square pan. Preheat the oven to 170℃.
Add sugar to the egg white and mix well until white. No need to whip.
Add jam and food colouring, and mix well.
Sift in the flour and baking powder, and mix.
Add melted butter by trickling it from a spatula into the bowl, and mix. Add half of the chocolate chips.
Pour the mixture into the pan. Sprinkle the rest of the chocolate chips on top.
Bake in a preheated 340°F/170°C oven for about 30 minutes. Poke a skewer in the brownie, and if it's clean, the brownie is done.
You don't need to melt the chocolate. Even so, this brownie has a strong chocolate flavour. I think this version is tastier than normal brown chocolate brownies.
I used natural food dyes for this. It is pale and gentle beige pink. This colour might be not pink enough.
I used red food coloring for the brownie above. The color is not too strong, so I recommend to use food coloring for this recipe.
Story Behind this Recipe
I kept thinking about how to add a beautiful pink colour to the brownies. I've baked a white cake from egg whites before, so I took a tip from the recipe, "Egg Whites Only Lemon Cake without Egg Yolks" Recipe ID: 732806. I guarantee the taste!
If you don't have white chocolate chips, finely chop a white chocolate bar. If you add jam only, the colour will be dull and not pink enough. Your house will be filled with a nice aroma from the oven during and after baking.
