my only word of caution... I have a son that has to touch everything! he touched the stove and burned his hand. I had turned the stove off so it wan't "red" anymore and he thought it wouldn't be hot any longer... and he touched it. I thought he knew and understood how hot it would be but he didn't, I thought I was so careful, because I accidently had my oldest burn his hand on the stove before so I thought I was more aware, but I wasn't, I forgot to tell my tactile learner that the stove will still be hot even after the "red" goes away.
I'm not a baker but a lot of baking uses a lot of hands on cooking. I think that would be fun. mixing different dough, with nuts or raisins would provide lots of different textures. I did make home made truffles one time and I had to roll them in my hands, it was great fun but very messy, but worth it because they tasted so good! you could always mix up a fruit salad and let her mix it up with clean hands, or a cold pasta and veggie salad.
what about playdough? or doing mosaic art with different materials, those would seem to be very tactile also. or maybe a blind fold game, where she has to guess things you are giving her, you could play it over the sink and give her foods and she would have to feel them and smell them and taste them, you could even use some of the food you are preparing for dinner that evening (of course the eating part may not apply to everything) I once was taken on a blindfolded walk all over my college campus and I had to touch and feel things along the way to figure out where I was, it was an amazing experience, (I still remember it and college was along time ago for me:)) oops sorry got off on a tangent there. I forgot it was a "in the kitchen" question.
anyhow... have fun!
