Cooking Mama 3: Shop & Chop

In all the Cooking Mama's you get a bronze, silver, or gold medal depending on how well you complete the dish. But on this one when I though I would get a gold medal (for a 100 score) for pickles for Gradma I got a sparkling happy face. Can you always get this happy face and how? I don't think I did anything different compared to gold medal levels. Does it have any meaning?The game so far has mechanics that are a tiny bit more difficult, but its very fun ^_^ And I get hungry whenever I play it >_<

I realized the difference is from whether you press the "make" button or the "serving platter button" under the "Let's cook" section. Does anyone know what this means?
