- I have a rice cooker here that's absolutely, certainly, never used for anything other than plain rice. The rice contains no flavorings, bugs, or anything else non-kosher.
- Rice is raw inedible and needs cooking.
- The way a rice cooker cooks rice was included on the Talmudic ban
- Rice is its own food and not secondary or a condiment
- Rice is a significant enough food that a head-of-state would eat it (Chazon Ish), or that it would be served at a state dinner (most American poskim).
This 100% kosher-ingredient rice would be non-kosher if made entirely by non-Jews, because of Bishul Akum.
The solution would be to get the Jew involved in the cooking. Which of these actions (or combination of actions) would be considered enough involvement?
- Adding rice or water to the pot initially
- Mixing the rice/water before starting the cooking
- Adding salt (okay assume plain salt is kosher) to the pot intially
- Placing the pot into the rice cooker
- Plugging in the rice cooker
- Turning it on (I assume we'd all agree that step works?)
- Fluffing the rice mid-cooking or post-cooking
