Mile High Biscuits

When were growing up my mom always made the best biscuits.  They were a baking powder biscuit that were so tender and soft.  As an adult, I was always hesitant to make them because they call for powdered milk and I never had it on hand and it was so expensive to buy.  I stumbled across this recipe and they were very similar (and possibly a tad better-sorry mom!).  Thankfully, this recipe just calls for milk and skips the powdered milk.
I have made this recipe numerous times lately and they always work.  I've even been making the entire recipe in my Kitchen Aid.  I've just added the shortening in smaller pieces and let the mix "cut" it in until it's the right consistency.  Then I add the liquids to the mixer and let it stir it up.  I still knead it on the counter a few times so that it's not over mixed in the mixer.

3 c. flour
3/4 tsp. cream of tartar
3/4 tsp. salt
4 1/2 tsp. baking powder
2 tbsp. sugar
3/4 c. shortening
1 egg
1 c. milk

Mix dry ingredients and cut in shortening until it resembles crumbs.  Mix the egg (slightly beaten) with milk and add to dry ingredients.  Stir to mix, then knead briefly on floured surface until well combined.  Do not over mix or handle.  Roll 3/4" thick and cut into desired biscuits shape.  Bake at 450 degrees for 12 minutes.
