What I am about to say may seem absolutely radical.
Buttermilk isn't milk that's one churn away from being butter. It's actually the leftover liquid that remains after butter has been made (kinda gross). It's sour and it does contain a few specks of butter from the processing.
I don't normally hear of people kicking back with a nice, cold glass of buttermilk. Most of the time it's used in baking recipes, and that's when I find myself running to the store for that "special" ingredient that I don't normally have on hand in your fridge. Plus, I have never used the entire quart of buttermilk and usually end up throwing the rest away. Totally wasteful. Not anymore!
To make Fake Buttermilk, simply mix:
1 Tablespoon White Vinegar or Lemon Juice
1 Cup Whole Milk
Let it sit for 5 minutes....and voila! You have "Buttermilk" ready to use in recipes like Fake Pillsbury Biscuits!
Now let's do the Fake-It Yourself Breakdown:Fake Buttermilk
1 Cup Milk $0.17 (1 Gallon Aldi Milk $2.80),
Total Fake-It Yourself Cost $0.17
Compare to Grocery Store Brand Buttermilk $1.69 Quart
Use 1 Cup and probably waste the rest.
Total Fake-It Yourself Savings $0.99
Not the biggest savings, true, but I saved a trip to the grocery store (gasoline & temptations) and I wasn't wasteful.
