Preheat skillet or pan.
In a measuring cup, combine milk and apple cider vinegar to curdle. Allow to stand at least 5 minutes
In a large bowl (or bowl of KitchenAid Stand Mixer) combine buckwheat flour, baking powder, baking soda, and cinnamon. Set aside.
In a smaller dish, beat egg. To that add applesauce, oil, maple syrup, and vanilla paste (or extract.) Mix until combined. Add to dry ingredients, and gently mix in.
Add milk & vinegar mixture to batter, ant whisk until completely combined and all dry ingredients have been incorporated.
ALLOW BATTER TO REST for three minutes prior to cooking.
After batter has rested, use a 1/4 c measuring cup to pour batter onto griddle. Cook 1-3 minutes until bubbles start to form on the side of the pancake. Flip and cook for 1 minute more. Repeat with remaining batter.
Meanwhile, to make Baking Mischief's Strawberry Sauce, place strawberries, sugar and water in a medium sauce pan. Allow water to come to a boil, and cook for 3-5 minutes.
If you put the strawberries in whole, use a potato masher to smash the strawberries. Remove from heat and add lemon juice and cornstarch combined with water. Return to heat and cook until sauce starts to thicken.
