Let’s Bake! (Petri Dish Jellies Edition)

So this isn’t technically baking, but I like keeping the title of the series. This was one of the easier creations from Nerdy Nummies, so last weekend, I decided to give it a go.

I ordered Petri dishes from Amazon, as that was the one part I didn’t have. The concept seemed easy enough, fill the dishes with jelly and get creative with the lollies on top to make it look like ‘bacteria’.

Here’s what you’ll need:

  • Jelly in different flavours (strawberry, blueberry, lemon, orange and lime) – with mine though, I only used blueberry and lemon, otherwise you get too much jelly. I used food colouring to get the different colours.
  • Lollies
  • Petri Dishes

That’s pretty much it!

Pour the jelly crystals into a heatproof bowl. Add one cup hot water and mix. Add one cup cold water and mix again. I poured some into separate bowls and made different colours. Then, I added them to the petri dishes!

I filled them up around two-thirds of the way and put them in the fridge. Let them set for an hour, before taking them back out to put in the lollies.

I just had fun with setting up the lollies. I tried to pick lollies that I thought would look more like ‘bacteria’. It was so much fun placing them all in the jelly. Once I was done, I put them back in the fridge to set even more.

That’s it! Another hour later, we were able to dig into them! I made 20, so there was quite a lot of jelly in the fridge. In the end I only used two boxes of jelly, so we still have three for a later date. I do recommend using food colouring instead of making five boxes of jelly. Cause then you have waaay too much! That all being said, I love how these came out! They’re so colourful and cute, and a little creepy!

I’d say they would be perfect for a kids birthday party! It’s nice to come home and have a little treat waiting in the fridge too 😀
