Do I have to peel the ginger?
No, as long as you scrub it well. Peeling gives a slightly cleaner flavor, but the skin is not a deal breaker. I usually peel if the ginger looks dried out or dusty.
Can I use brown sugar or honey instead of white sugar?
Yes. Brown sugar makes it more caramel-like and a little darker, which is great for coffee and fall drinks. Honey works too, but keep the heat low so the honey flavor stays pleasant. Expect a slightly thicker syrup and a different sweetness.
How do I make it stronger and spicier?
Slice the ginger thinner, simmer 2 to 3 minutes longer, and steep 20 to 30 minutes. Taste and stop when you like it, because pushing it too long can tip into bitter or overly vegetal.
Why did my syrup crystallize?
Usually it is undissolved sugar, evaporation from boiling too hard, or stray sugar crystals clinging to the sides of the pan. Stir until the sugar fully dissolves, keep it at a gentle simmer, and avoid splashing sugar up the sides. If it crystallizes anyway, rewarm gently with a splash of water and stir until clear.
Can I use powdered ginger?
You can, but it tastes flatter and can get a little gritty. If you must, whisk in 1 to 2 teaspoons, simmer briefly, then strain through a coffee filter or fine cloth.
What is the difference between ginger syrup and ginger simple syrup?
Same idea. “Simple syrup” usually means equal parts sugar and water. Adding ginger makes it ginger simple syrup. This recipe is that, with a short steep for more flavor.
