## L. Halvah

Time limit: 1.0 second
Memory limit: 64 MB
Ingredients:
2 cups sunflower seeds
1.5 cup flour
0.5 cup sugar
0.25 cup vegetable oil
0.5 cup water
Practice shows that after saving the world one needs to eat a piece of halvah made according to a classical recipe.
Grate sunflower seeds and toast them on a frying pen. Fry flour on a dry skillet, stirring thoroughly until the flour gains a cream color. Then, mix flour and grated seeds well, and grate them together once more. Add oil and mix.
Mix water and sugar in a saucepan and bring to boil. Boil until the sugar dissolves, then pour this syrup over the flour-seeds mix, and mix well until an even consistency is reached. Place in a refrigerator until the halvah turns hard.
In the end you will get 700 grams of halvah.
