It is true what researchers claim: that smell can invoke memories. With the tip of my nose into that little jar, I strangely found myself back in my parents' home, as a kid with my three school-going brothers. (Our eldest brother G and sister R were already in campuses out of town.)
This usually took place on Sunday afternoons when Dad was in charge of the household, including lunch. *cringe* Back then, Sunday was a normal school-day for Mom. And she wouldn't be back till after 2pm. Dad would turn the four of us into a team of "house cleaners": the youngest (yours truly) dusts and wipes, the next youngest (S) sweeps, the next (M) mops. While the eldest of the four, R, cleans the compounds around the house (front porch, side garden, back yard). Smart Dad. He'd tire us out by doing the chores, and by lunch time, we'd be so hungry we'd eat anything.
So what has this got to do with the light soy sauce and dijon mustard mixture?
