Fresh ginger is super cheap! You can break off a little knob the size you want, at the grocery store and just get that. It usually costs like under 50 cents. For spices, Penzeys.com is the best! They’re the highest quality spices I’ve ever found, incredibly flavorful, and they’re the same price (or less) than grocery store ones. I live near one of their stores and have had to buy another spice rank because I’m so obsessed. If you sign up for emails they always have free ones too.
