These are the best biscuits ever. Grandma Amos was my mom's mom, who raised her children on a farm near Alexander, MB. Grandma’s trick is to “spin” each biscuit between your hands (after it’s cut) on a floured countertop so that you very gently bring the sides of the biscuit in and make the biscuit taller.
Mix the dry ingredients, cut the butter into the dry ingredients until they are pea sized and give them a toss. Add the milk and stir enough just to mix. Turn it out onto a floured counter and gently fold dough until it comes together (DO NOT knead like bread). Roll it gently to about 1.5” thick and cut with a round cookie cutter. As you reroll your leftovers, be gentle.
Bake in a hot over (425° F - 450° F) for about 15 minutes. Once the bottoms are nice and brown, they biscuits are done!
