Never used one, never taken a measurement. I just watch what my plants are doing and adjust accordingly. You can have too much information, in my opinion.
Dude, if you like garlic…you gotta try my garlic mashed potatoes recipe. Sorta a spin on Julia Child’s recipe.
First, roast 30 cloves of garlic (or use pre roasted from the olive bar at the nice grocery store)….once soft and golden brown, mash with a fork, or mortar and pestle.
In a small saucepan, melt half a stick of butter, add a cup of heavy cream, add garlic, season with S&P. Cook on low-medium low for about 15-20 minutes, stirring often.Not really trying to reduce, but infuse here.
Boil two and a half pounds of large diced potatoes in salt water until tender….drain, reserving 1/2 cup of liquid. Mash potatoes, add reserved cooking liquid, and garlic and milk mixture and stir until incorporated. Season with s&p to taste. Voila
Best potatoes on the flat earth.
