Our other recent mixing activity was rather less tasty - playdough. I found a recipe for it here, and K had fun cooking it up.
Then we divided up the dough and worked in some food colouring to make red, blue and green dough as well as leaving some plain. That's what H was doing in that picture I posted yesterday :-)
After that it was just a matter of playing! The dough was not too sticky and generally quite nice to handle. It reminds me a bit of Silly Putty, in that it will stretch but it will also snap if you pull it quickly. Still, I think the one that Mum used to make for us when we were little was better. Do you still have the recipe Mum?
