My Dad frequently quoted Bob Hope's line from an advertisement, "Now, you're cooking with gas!" It meant, "Now, you're on the right track," or "Now, we're making progress." I thought of him when I fired up my brand new Viking stove for the first time because, literally, now I was cooking with gas!
When I turned on the oven to roast its first chicken, it went from cold to 400 degrees F in about five minutes flat - it uses the broiler, which is like a mini-inferno - to preheat. This in contrast to my old oven, which might or might not be ready to roast in about 30 minutes.
The burners on top melt butter right now, and boiling water for pasta is immediate rather than eventual.
The racks glide like skates on ice and the light inside really lights!
Needless to say, I'm in love.
