Why do we add salt to cakes?
Salt is the main function in cake recipes is to enhance the flavor of the other ingredients.A salt makes sweet things taste sweeter. It modifies flavour, increases crust colour and controls the rate of yeast fermentation and enzyme activity.
For the right dessert, salt will improve texture, make citrus fresher, render spices more aromatic and help dark chocolate and cocoa taste less bitter. Same is true with bread dough, just a little salt takes the flavor from flat to full.
Adding a pinch of salt to batter won’t give the cake a salty flavor. Rather, salt reduces bitterness and allows sweetness to come forward, producing a more well-rounded flavor.
A little pinch of salt in a chocolate recipe can enhance the overall flavor without tasting salty. Of course, salted caramel has become ubiquitous.
So, Obviously you can use small pinch of salt..
