Just One Ingredient

Monday moved into Tuesday and Simmy had some quiet time to reflect... on her fixation with making 'bread' these days.
'Bread is one of the most difficult baked goods to perfect," she thought to herself.
If you were a good bread maker, well,... then,... in the 'sewing circle' ladies' group you were admired. I don't just mean a nod of approval but that kind of admiration that earns you the royal crown of baking. Simmy's mother, yes, the 'parrot stew' mother, had definitely earned that crown.

Her buns were highly esteemed by all and sundry who had the fair luck of having eaten them. 'Locka' was the word which was burned into Simmy's mind. In translation that word means 'light and airy.' Now, one must realize that this definition is combined with the experience of eating this perfect bun in the presence of the Queen of Baking and when, in that moment, she would dub the bun 'locka'... well,...
That is how I learned what a perfected bread was, is and will ever be... that sounds like a sermon. Sorry!
I have since come to have my own opinions about good bread and, Shh! Don't tell the queen!, but my definition of 'locka' is different than my mothers' definition. Oy!
But, I still don't have my own recipe down pat... or have I stumbled across the ingredient that makes all the difference?

Please don't judge the painting too harshly... my friend gave me some paints, brushes and a couple of canvases and being of the 'frugal' sort... I had to try to use them.
Anyway, while making these buns yesterday for dinner... I changed one ingredient, just one. I used a different oil than all the ones I've used in the past... and these buns are the softest, most amazingly tender buns I've ever made.
Just one ingredient change... made all the difference.
