How to change servings in a recipe?

I saved a recipe of mine to the database, which makes 6 servings. I wasn't too hungry tonight, so I only had one-half of a serving - how can I enter that in my food log? I don't want to change the entire recipe to 12 servings.

Thanks.

You just need to go to the recipe, then click to add it to your food log.  Once the nutritional information page comes up, you'll want to click on "Values per 100 grams" and change the value under "weight" to the grams you actually ate  (whatever 1/2 serving comes to).  Then the nutritional/calorie information will change accordingly and you can add it to your food log!
This is great for if you ever have leftovers as well :)

Beauty! Thanks.
