What is the difference between medium roast and dark roast coffee?

The darker the roast, the less caffeine and acidity. The color of deeply roasted coffee beans ranges from satiny chocolate to shiny brown. The darker the roast, the more burnt it tastes and the lighter the flavor of the coffee beans. Deeply roasted coffee beans have a smoky flavor and are more suitable for making ordinary coffee, but not for making espresso.

Raw coffee beans themselves do not have any coffee aroma. Only after they are roasted can we smell the rich coffee aroma. Therefore, roasting coffee beans is a transformation process of the internal components of coffee beans. Only after roasting, the components that can release the coffee aroma are produced, and we can smell the aroma of coffee.

Roasting is roasting coffee beans at high temperatures, or roasting, to create the unique color (similar to amber, depending on the degree of roasting required), flavor and aroma of coffee. Roasting turns the light green (or light yellow) raw coffee beans into the familiar tea brown coffee beans. High-quality roasting means that the aroma, sourness and bitterness of the raw coffee beans can be cleverly expressed.

What can egg whites be used for baking?

The baked goods that can be made with egg white include: meringue, angel food cake, double skin milk, egg white coconut balls, almond protein crisps, etc.

Egg white refers to the transparent gelatinous substance composed of protein surrounding the egg yolk. Therefore, it is also called egg white, as opposed to egg yolk. Egg white will solidify into a white solid when exposed to heat, hence the name. Egg white has the same shockproof, moisturizing and protective effects as the amniotic fluid of mammals. If you use a high-speed egg beater to stir the egg white, it will become foamy and elastic like a sponge. It is the first step in making cakes.
