According to my knowledge few tips are available :-

1. When cooking for guests, be sure to let them know when you cook with pine nuts. Most people who are allergic to more common nuts are also allergic to pine nuts.

2. Pine nuts may be eaten raw but are usually roasted or toasted. As with most nuts, toasting brings out more flavor.

3. Roast raw pine nuts on a flat tray in a 350-degree F. oven for about 10 minutes, shaking halfway through. They may also be toasted on top of the stove in a heavy skillet, stirring often until they turn golden.
