I used to avidly collect cookbooks until I realized I never used them. Not all of us have a fully elaborately stocked pantry, or enjoy cooking for hours on end.
I'm more of a 'what have I got' and ' what do I feel like having' type person.
When I cook I kinda get in the zone and cook via my taste buds....it's a little like a frenzy with me going taste, taste, taste, add, add, add.
But things like cookies and cakes I get the feel of a recipe....and when I know it well, I start experimenting. I like to make things as healthy as possible, so I often try to remove sugar and replace sweetness with fruit, honey or more natural sugars.
I thicken a lot of dishes now with egg, or ground flax seeds instead of flour if I can.
I'm also a lazy cook ....it has to be quick or I end up not wanting to eat it.
