My boys love it when I give their dipping sauces a little personality. The best part is that it's very easy to do and takes only seconds to do.
The trick is to use a mini cookie cutter. A toothpick, chopstick, or the tip of a butter knife will do.
Decide on how you want to arrange your food first, especially if you're trying to go for a theme. Then place the cookie cutter on your plate.
Use one hand to hold the cutter in place and the other to squeeze in the sauce. Bottles with easy squeeze lids help, but again a butter knife will work if you need to scoop the sauce out of a jar. Make sure that it's a thicker sauce, as it might not hold its shape if it's a thin runny relish for example.
Grab a toothpick and move the sauce all around. If you're holding the cutter firmly you can even bang up against the edges. I like to move in small circles to help create a flat surface and do this pretty quickly.
Remove the cutter by lifting straight up in one motion. If you wiggle around too much it might ruin your shape. So far I haven't really had that problem though. If there's any mistakes you can always take the toothpick and adjust it a little bit.
If I royally screw up, I'll just take a paper towel and wipe it away, or rinse off the plate real quick. It takes me only so many seconds for each shape,
Fun Ideas and Tips
Make it sweet! Use pudding, greek yogurt, or Nutella.
Put it on top top of a sandwich or hamburger, set the top piece of bread on the side for them to place.
Mix condiments together. ex. Ketchup and mayonnaise for pink.
Keep it simple, don't spend forever on it. Less is more here, you're going to a fun element that's supposed to be easy to do.
Use two toothpicks to apply sauce on top of another sauce (like I did for the mouth and eyes on the bear)
Wipe the cutter between uses for a cleaner approach.
Prep the sauces on the plates before adding other foods. Much easier!
