Our stir-fry machine operates on the recipe axiom,

$$\textit{Stir fry} = \textit{Constant ingredients} + \boldsymbol{\mathit{Variable\ ingredients}}$$

Expanding with individual ingredients by relative volume (variables bolded),

$$ \begin{aligned} \textit{Stir fry} &= 2\; \textit{Ginger} + 2\; \textit{Garlic} + 3\; \textit{Scallion} + 3\; \textit{Soy sauce} + 1\; \textit{Sesame oil} \\ &\quad + 4\; \textit{Neutral oil} + 125\; \boldsymbol{\mathit{Protein}} + 3\; \boldsymbol{\mathit{Acid}} \\ &\quad + 2\; \boldsymbol{\mathit{Sugar}} + 2\; \boldsymbol{\mathit{Umami}} + 125\; \boldsymbol{\mathit{Veggie}} + 1\; \boldsymbol{\mathit{Extra}} \end{aligned} $$

The machine will randomize the ingredients to be used as variables.
