Essentially to sneak veg in to sauces for my VERY fussy DS. I’ve got a magimix food processor and a stick blender which is what I would always use for baby purees and soup,etc. Never really had issues but looking at recipes for hidden veg sauces and the photos do look as if it’s completely smooth. Is this actually possible? My kids would always be able to spot the flecks of veg. Now wondering if I should invest in a jug blender or nutri bullet? Have I been conned by marketing?
