Caramelizing—truly caramelizing[0]—onions is a slow process that takes close to an hour. For this kind of task, I think it’s helpful to be able to set timers and be in and out of the kitchen, rather than be stationed at the stovetop continuously.
I like the term “making biscuits” better than “kneading” or “kneading biscuits”. Butter biscuits (and scones) usually require handwork to integrate the butter into the dry ingredients. In my experience, this handwork pretty closely resembles what the cats are doing. There’s a lot of squeezing going on to break up the cold butter and mix it in.
