The main difference between garlic powder and granulated garlic is texture. Both are made of dehydrated garlic. Garlic powder has a very fine consistency, more like flour. Granulated garlic is coarser, more like the consistency of cornmeal.
Advantages of Granulated Garlic
- Less likely to clump as compared to powder
- Better for salad dressings, sauces and soups. It combines better with liquids
- Better for spice rubs because it will mix more evenly with other spices
- The preferable substitute to fresh garlic
Advantages of Garlic Powder
- The powder form is more potent than the granulated form
- Better for recipes with short cooking times. It will release flavor faster
- Better for marinades
- More intense garlic flavor
Substitution Recommendations
Because garlic powder has a finer consistency, the same amount of granulated garlic will be less potent. If your recipe calls for powder and you are substituting granulated you should increase the quantity.
