In a medium saucepan over medium heat, combine sugar and water until the sugar dissolves. Add the lavender flowers; stir until mixture comes to a boil; reduce heat to low and simmer 5 minutes. Remove from heat, cover, and let stand approximately 10 minutes.
Place a fine strainer over a large bowl and pour syrup mixture through (straining out the lavender flowers). Add lemon juice and vodka to the strained syrup mixture; stir until thoroughly blended. The vodka (or any other type of alcohol) is the secret to a soft sorbet. Alcohol itself does not freeze and adding a little bit keeps the sorbet from doing the same. Vodka is excellent to use because it doesn't affect the taste.
Ice Cream Maker - Transfer mixture to ice cream maker, process according to manufacturer's instructions.
Freezer Method - Pour into container, cover, and place mixture in the freezer. When it is semi-solid, mash it up with a fork and refreeze again. When frozen, place in a food processor or blender and process until smooth. Cover and refreeze until serving time.

Makes 8 to 10 servings.
* When using lavender in your cooking, use 1/3 the quantity of dried lavender flowers to fresh lavender flowers. If you add too much lavender to your recipe, it can be like eating perfume and will make your dish bitter. Because of the strong flavor of lavender, the secret is that a little goes a long way.
