"Mastering the Precise Flavors of Top Chefs at Your Command" BOTINKIT MAX can automatically dispense 12 types of seasonings (6 liquid seasonings + water-dissolved potato starch, 5 powdered seasonings) with high precision, enabling stir-frying and simmering similar to a Chinese wok through automatic control of the pot's angle, rotation, and heating amount. This authentic stir-frying method sets itself apart from cooking with fryers and steam convection, greatly expanding the possibilities for menu offerings. Recipes that chefs take pride in are stored in the cloud, allowing any restaurant equipped with BOTINKIT MAX to produce dishes of the same quality, regardless of who is cooking. "Freedom from Pre-Mixed Seasonings" To standardize the flavors of the dishes served, cooking reliant on "pre-mixed seasonings" has become common. While convenient, pre-mixed seasonings lead to uniform flavors and make it difficult for cooks to showcase their skills in the dishes. BOTINKIT MAX can automatically dispense 12 types of seasonings at the right timing and in the right amounts, allowing for the automation of "handcrafted" techniques, such as sautéing aromatic vegetables in oil to release their fragrance, which was previously challenging with pre-mixed seasonings.
