I found this version on the blog adelynSTONE, check out her post for great step-by-step instructions. I have seriously made at least 30 batches of this stuff- it's wonderful! You probably have most, if not all of the ingredients in your cupboard right now. Each batch takes just over 5 minutes - start to finish - to make.
The Best Playdough Ever
1 cup water
1 cup flour
1/4 cup salt
1 Tablespoon oil (any type - I have used both vegetable and olive oil)
2 teaspoons cream of tartar
food coloring or a kool-aid packet
1. Combine all ingredients in a large sauce pan.
2. Stir the dough constantly over medium heat, until the dough comes together into one ball.
3. Knead a few times for uniform consistency.
A few tips & tricks I learned along the way:
I initially bought a bunch of kool-aid packets to color the playdough with, thinking that they would add a fun scent. While you can smell the flavors, it is very very subtle, and personally it didn't really seem worth the 10-cent investment for each batch. I would suggest just using regular food coloring, and adding in a drop or two of essential oil to create a scent, rather than the kool-aid. But, if you have extra packets laying around - they do fine at adding fun color to the dough!
The first few times I made this playdough, I whisked together all of the ingredients until no flour clumps remained before bringing it to heat on the stove. Later, I tried just stirring everything together as it was heating - I didn't notice any difference. The clumps made their way out of the dough just fine as it thickened up.
Your dough will become slightly darker color once it is done, then before.
If you are making multiple batches, no need to clean out the pan each time - just start with the lightest color, and work your way through your palette.
I would not suggest making more than a double-batch at a time - it will take much longer to cook, and will be very hard to stir!
