Once I discovered a stick blender my life changed. Its brilliant and really, you don't need anything else to puree sauces or even makes smoothies (not that I would dream of making the latter!). The great thing is that the end screws off and you just rinse it under the tap. Washing up done!I was watching Anjum Anand on television yesterday evening and she always appears to use a stick blender. I've never had one. I always use the table standing type (blender).
The only issue is that if you use it in a shallow pan with not much in it the food splatters. But as long as the head of the blender is immersed, you can use it directly in the pan you are cooking with. Otherwise, I use the 'beaker' which came with it.
