This is the stuff:
It's pricey online; you might be able to find it at Kroger/Fred Meyer affiliates.
I feel like you either haven't tried skyline chili, or you haven't tried putting regular chili on spaghetti.
Oh! Or looked up a recipe online! Those don't work, and I don't know why. Best I can do without going to Ohio is using these packets from amazon. Here
1 lb. ground beef (lowest fat content possible, like 93/7%)
1 6 oz. can tomato paste
6 cups water (I usually use 4-5, to cut the cooking time)
1 packet of spice mix: Amazon, but Walmart is probably cheaper
Scrape the beef into the water, beating it with a fork to break up lumps; bring it to a boil. (Do NOT brown the beef first!) Reduce to low heat. Add tomato paste, stir, and add the spice packet. Simmer until the chili "snaps back" when stirred.
Serve over spaghetti noodles; top with finely-grated sharp cheddar cheese and red pepper sauce (tabasco or Frank's). This is what's called a "3-way," a 4-way" includes diced onions on top. IIRC, a 5-way adds black beans. (I don't use onions or beans, so I could be misremembering.)
For coneys, put a hot dog on a bun, top with mustard, and add a ladleful of chili and a handful of cheddar; add hot sauce again.
If you have relatives or friends in the Midwest, they may be able to pick up the spice packets at a Kroger's store or subsidiary.
