From scratch hot chocolate:

2 mugs full of milk

enough powdered cocoa (plain) to make it taste the way you like it

sugar to taste

a tiny pinch of salt

arrowroot or cornstarch (about 1 teaspoonfull)

almond extract to taste (probably about 1/8 to 1/4 teaspoon)

Mix dry ingredients together in a saucepan. Mix wet ingredients in a separate container. Gradually add the wet ingredients to the dry, mixing carefully to break up lumps, until all is incorporated. Heat over medium to medium high heat, stirring constantly, until mixture thickens somewhat. Enjoy.
