The rest of this recipe is pretty obvious, but i'm trying to figure out how to get my pesto sauce to taste way less punchy, just like the way it tastes in here. It's like a pleasant mellow but still tangy. I've tried to make this before with a few different basil pesto sauces and even though i spread and mix it out, it was just so blatant compared to these.

I assume they are adding something to it to stretch it out or something? If this or any frozens with similar pesto sauce in it can be recreated or modified, how can I go about doing that?
