This is literally ginger beer!
Put 2 cups of sugar in a large saucepan.
Add 6 cups of water.
Roughly chop 2 cups of ginger into large chunks (you don’t have to peel it)
Then put the ginger chunks in the food processor.
Add the ginger puree to the water and sugar.
Put saucepan on the stove and bring it to a boil, then turn it down to simmer.
Simmer it for an hour, then strain it to remove the ginger.
You’ll want to mash down on it to get all the syrup out.
Store in a bottle.
Add 2-3 Tbs. ginger syrup to your favorite lager (Okay, fine. You could add it to seltzer, too.)
