What type (semi sweet, dark, etc) of chocolate do you recommend?

It's a matter of preference or whatever you have on hand. I like a dark or semi-sweet since the bitterness compliments the sweetness from the strawberries.

Hi Cynthia! I just consulted the recipe author. You can choose any kind you enjoy—it's a very small amount so it's ok to go with your preference. I also updated the ingredients list with this detail.
