Toum coming out with a VERY strong spicy raw garlic flavor.

The first time I made it I used store bought peeled garlic, cut them in half, used about 2 cups along with a bit of salt, lemon juice, water, and oil, and used an immersion blender. It came out perfect.

The next 3-4 times, using the same garlic, as well as trying with fresh peeled garlic, I am not getting the same flavor. Instead, I’m getting that spicy, raw, throat burning, garlic flavor. I even removed the sprout from the garlic and it still came out the same. The very first time I did not do this and it tasted great.

Any ideas as to what I’m doing wrong?
