I love Pop Rocks! 
So a homemade variety sounded great!

This recipe makes a tart and fizzy treat...not the same as the store bought stuff...
but really fun to make with the kids!

1/2 cup light corn syrup
1/4 cup water

1 teaspoon flavoring extract, flavor of your choice
3-4 drops food coloring, color of your choice
1/4 cup citric acid

In a saucepan, combine the sugar, corn syrup, and water.
Cook the mixture until it reaches 300 degrees (hard crack)

I use a candy thermometer.

Step 3: Add the fun, flavor and fizz!!!

Remove from heat

add the baking soda
¼ cup of the citric acid
extract (we used one dram of strawberry)
food coloring
(we only did 2 drops and it pastels the
color so I'd go with 3-4 drops)

Step 4: Mix and pour...

Cool completely, about 30 minutes.
Break the candy into pieces.
I just used a butter knife...
You can break it up into small pieces,
then put some in a plastic bag and hammer them
into little pebble pieces!

Store in Ziploc bags.

Step 6: Try it out!

The candy is filled with holes from the baking soda!
This is supposed to be the magic coupled with
citric acid to get that pop effect!

They are really crystally and cool looking!

No, not like store bought Pop Rocks...
That are sweet and explode in your mouth...

It was sort of fizzy and sometimes bubbly in
your mouth...but slightly sour!

Not too sour for me or my daughter...
(who's nick-name involves the word 'lemons'...because she loves lemons)

Was it fun to make and eat?
YES!  And it's super fun to watch them eat it!

hiiii, i made it and it has been almolst 5 hours and it still has not hardened even a bit.

Would it be possible to make this with a pop flavour? For instance, orange soda, or something that already has the citric acid in it.

I really want to make this but can you tell me how many millilitres are in a cup?
A little know trick to most is just use Google :-) If you Google 1 cup to ml it will tell you. The same for 22C to F Google has lots of built in calculations it can do for you.

I am sure that there's a conversion calculator on the internet somewhere...figure it out and try it! :)

Also, is there a neutral citric acid I can use or is bottled lemon juice okay?
Arcan3 tedbear22 years ago
yes there is, i think (dont quote me on it) unflavored vitamin C is mostly citric acid.
vitamin C is ascorbic acid, not citric acid. You can use vit C and any other acidic material. the fizz come from the reaction between baking soda (base) with acid.

This reminds me of the Pop Rocks 'ible I made for the candy contest a couple years ago.... Nice job
doodlecraft (author)  chickflix2 years ago
Oh, no way! I didn't even check! :) Great job to you!
Yup, I made it for the last candy contest.

If you want to be extra creative and a bit inventive. Then whilst this is still very liquid put it in a container that can be pressurised and pressurise it with C02. try and agitate it as much as possible whilst under pressure and let it cool without depressurising. The little trapped bubbles will now be at a higher than atmospheric pressure and will give you the popping in your mouth sensation.

Remember to brush your teeth after this! Citric acid is a great cavity mining tool.

I was wondering, could you substitute something like some unsweetened powdered drink mix for the flavoring extract and food coloring or would that change the recipe too much? This looks like a fun Instructable to do!
doodlecraft (author)  ldeese12 years ago
Great idea, your guess is as good as mine! Try it and let us know! :)
Sounds like this makes something similar to Fizzies instant "carbonated" drink tablets -- but these might be better! I'm gonna make some pdq :-) thanks for the Instructable! I voted for ya :-) www.sweetcelebrations.us #sugardome
Yummers! I would love to try to make this!
