There is bottled minced Garlic and freeze-dried minced Garlic. 1 medium-size clove Garlic equals 1 to 1 1/2 teaspoons bottled minced garlic, this is around 5 g / .18 oz. So for 2 cloves you should add 2-3 teaspoons. You need about 50% less for freeze-dried minced Garlic.
The jar says 1/2 teaspoon equals approximately 1 clove of garlic, so if you want to stick directly to your recipe, I'd go with that, meaning 1 teaspoon for your total recipe. I agree with the heaping teaspoon advice you've already received, as I find it easy to underestimate.
