I have the Sous Vide, the siphon, the chemicals, no interest in the smoking gun or the anti griddle, would be more inclined to reproduce the ones that use a quick dip in liquid nitrogen though one can purchase a dry ice maker that uses a tank of CO2.
I do plan on having fun with my ebook edition of Modernist Cuisine - I love the idea of using the pearls to flavor boost drinks, and noodles made of agar agar and flavoring liquid. I have in mind a noodle of spinach and agar agar, some flavor pearls of mrAru’s balsamic dressing and thin slices of sous vide london broil as a sort of salad, I am thinking slivers of jicama for crunch. Not sure about croutons, I need to read more about playing with breads.
