Crave a roast dinner after work, but too hungry to wait two hours while your joint cooks to perfection? The answer could be LG's SolarDOM speed cooker. This electric oven needs only 35 minutes instead of 140 to roast pork (saving up to 50 per cent energy). It also functions as a microwave, grill and convection oven. The SolarDom costs $4,490 and is available at Fortress ( www.fortress.com.hk ).
