My mother had a double oven and four gas rings on her stove setup so I was in cooking heaven. This was fabulous for cookie baking day, holidays or any time we wanted a warm dessert with a hot meal.
I’ve got four gas rings and a long griddle ring. I tend not to use the griddle ring but I often have three rings going at once and use the fourth one to warm plates or set a lid down. If I’m cooking something that needs to come off the heat right away (cream sauce for example), I can just slide it over to the unused ring to prevent burning. I’d love a professional setup but I truthfully don’t need one.
Standard American gas burners seem to be cheap anyway – I’ve got a second burner inside, rather than that big flat cap, so each position is either large / small or medium / tiny. (The stove controls are all two-sided). I don’t need a simmer location to get a simmer burner.
Those cast aluminum bases are replaceable. On a commercial stove, they are replaceable with other sizes. On your stove … I have seen third-party replacement burners advertised, to upgrade the cheap standard American burners to star shaped. The star shape puts jets in the center as well as around the the edge. I didn’t pay any attention, because (as described above) I don’t need that kind of upgrade, but the point is that there are third-party upgrades suitable for some stoves.
Jewish kitchen: Self Cleaning double oven. But the house my friend bought was from a first-generation Italian family with a double oven and a grape press. As my Italian student explained: once every two months, he had the extended family around for dinner. Which was a major hit on his pocket (and he didn’t have much to start with). He was explaining that he had large pots that were used every couple of months.
But it meant that on all other Saturday nights, he, his wife and his kids, never ate at home, which evened it out.
When my last stove died I replaced it with a 2-burner induction cooktop, a microwave and a large countertop convection oven. All of which sit on a low dresser. The pans and lids fit nicely in the drawers, with a drawer for baking pans and one for plastic wrap, zip-lock bags, etc. As I live alone, this does nicely for me.
The dresser is one sort of like this - long and low, so the burners sit beside the stacked microwave & oven. Occasionally I wish for a third burner, and I have an extra induction burner just in case. My toaster over is large enough to roast a chicken, bake 2 loaves of bread, or do a large take & bake pizza. So while I’m not cooking for 30, as my mother sometimes did, it’s more than sufficient for my needs.
How has its reliability been? I won’t install another over-the-stove microwave: we’ve owned 3, all of which have gone bad within 5 years, The first one in this current house had a convection feature, which we never used. So I would worry about something with all those features combined into one.
Our double oven does have convection, which we’ve used on occasion.
It’s an all new house with all new appliances. No problems over two years, but that’s not a long span to judge. It’s a German brand, Siemens, which generally has a good reputation.
