Eat Your LEGOs!

This is a 2 part project.

1. How to make food safe molds for ice trays, custom chocolates or other shaped treats.
2. My recipe for healthy and colorful frozen yogurt.

I chose to make a mold of LEGOs since I had them around and owe much of my inventiveness to LEGOs. You can make a mold of anything using this process. If you are planning on using the mold for food, make sure your silicone is food safe!

Mold Making

1. Pile of LEGO bricks
2. Smooth-on Sorta Clear 37
3. Paper cups
4. Spoon or Popsicle stick

Recipe

1. Greek Yogurt
2. Honey
3. Vanilla Extract
4. Raspberries
5. Blueberries
6. Orange juice
7. Food coloring (optional)

Start by washing your LEGOs to get any dust or oil off of them. A bowl full of warm water and dish soap is perfectly fine.

Build your LEGOs like I have in the picture. The isolated LEGOs in the center are the ones that are going to end up making the mold. The ring of LEGOs on the perimeter will act as the wall to hold your flowing silicone in place. Make sure the LEGOs are pressed down well to keep the silicone from leaking out.

I chose to use Smooth-on Sorta Clear 37 because it is food safe. It can be quite thick if it’s old so sometimes it doesn’t flow well into super small features. It’s not toxic so there is very little safety concern but you can wear gloves since it’s sticky if you get it on your hands.

Calculate or measure how much silicone you are going to need. I did this by pouring water into my LEGO mold and then poured that water into a measuring glass. Shake the cans before opening and then pour part A into the cup and then pour part B on top of it. Use a spoon or Popsicle stick to mix it thoroughly for about 1-2 minutes. It may create some bubbles but don’t worry about this, it didn’t affect the end quality of the mold.

Slowly pour the silicone into the lowest point and let it wash over your parts. If you pour it all over your parts, you will get big bubbles in the final mold. If you notice it is leaking out anywhere, you can press the LEGOs down more or use tape to seal up some cracks. Now leave it alone until it’s cured (about 4-6 hours).

This is the satisfying part!

Once it’s cured, peel the LEGOs apart and remove your new mold! You may have some flash (the extra bits hanging off the mold) but that is easy to cut or pinch off. Give it one more wash in warm soapy water and it’s ready to be used!

This is a simple and healthy frozen yogurt recipe that makes the LEGOs pop with color!

Ingredients:

• 2 cup Greek yogurt
• 3 tbsp honey
• ½ tsp vanilla extract
• ¼ cup raspberries (for pink)
• ¼ cup blueberries (for purple)
• 1 tbsp orange juice (for orange… duh)
• 1 drop of food coloring (for custom colors)

Mix the Greek yogurt, honey and vanilla extract together in a bowl.

For each different color you want, add ½ cup of the yogurt mix and the ingredient for the color you want in a blender. Blend together for about 30 seconds until the color is consistent.

Pour the colored yogurt mix into your mold. For best results, pour the mix slowly to make sure you don’t trap too many air bubbles. You can use a knife or toothpick to stir the mix in the mold to get rid of even more air bubbles.

Put the tray in the freezer for 2 hours and enjoy when they are ready!
