What size should a rice cooker for singles be?
For one person, 0.3 to 0.8 litres is enough: the Reishunger Mini (0.3 L) is the true one-person mini, while the Russell Hobbs (0.8 L) offers some reserve and a steamer insert. For 1 to 2 people with occasional guests, 1.0 to 1.5 litres is practical (Reishunger 1.2 L, Rommelsbacher 1.5 L). Rule of thumb: better a bit of reserve, as the minimum fill level is usually low.
Is a fuzzy logic rice cooker worth it over a simple one?
A simple one-touch rice cooker (Russell Hobbs, Reishunger 1.2 L) heats and switches to keep-warm when the temperature is reached: cheap and entirely sufficient for standard rice. A fuzzy logic unit (Yum Asia, Reishunger Digital) regulates temperature and time by microcomputer for each rice variety: better, more even rice, especially with wholegrain and sushi, but more expensive. Heavy rice eaters benefit, occasional cooks not necessarily.
Rice cooker with steamer insert: what is it good for?
With a steamer insert you cook vegetables, fish or chicken over the boiling rice: a complete dish in one go, which saves pots, space and energy. Most appliances in the comparison come with an insert (Russell Hobbs, Reishunger 1.2 L, Yum Asia); only the 0.3 L mini has none (available separately). For single households in particular, steaming is a practical added value.
How does the keep-warm function work, and does the rice dry out?
After cooking, the rice cooker switches to keep-warm mode automatically and keeps the rice warm and ready to eat. After a very long standing time (several hours) the rice can dry out at the edge, which is true of all units. Tip: fluff the rice briefly right after it switches over and keep the lid closed.
Which inner pot is better: ceramic or non-stick?
Both are non-stick coated and easy to clean. Ceramic (for example Reishunger, Yum Asia) is considered harmless (PFOA-free) and gives off heat evenly, but is sensitive to scratches. Classic non-stick pots (Russell Hobbs) are robust and cheap. With both, use wooden or plastic utensils instead of metal so that the coating lasts.
