Take a mixture of apple, pineapple (include the crushed fruit if you want), ketchup (catsup if you prefer), apple cider, red wine vinegar, soy sauce, garlic, and sugar.
Add some cornstarch to make it thicker and the result is a beautifully sweet and sour sauce that can be worked into any number of delicious dishes.
I’m not a fan of the Chinese Communist Party but if there is a real General Tso, then he has our admiration for his chicken. In this case, the opposing flavors go quite well together but there are a few other examples where opposites mix well. Salt and pepper is another opposing culinary pair that the two of us always enjoy. Cats and other animals can live peacefully under the same roof. Saints and sinners often marry each other and as the two of us believe from the old movie “The Odd Couple”, even slobs and neat freaks can find respected ground. In the 1970s, one of the more important pairings of opposites occurred when a home’s natural gas furnace was combined with a compressor and indoor evaporator equipment to form more complete equipment that could hot the new home in frosty weather and keep it cool while in the hottest summers. Central Heating and A/C systems eventually became the norm, replacing the old stand-alone gas furnace and one or more window AC units. The homeowner now controls the indoor temperature with one control equipment that uses both heating and cooling. The result was cleaner air, improved circulation, and reduced sound because the noisy compressor equipment could be set some distance away from where the newer home renters were situated. The future of Heating and A/C is likely to include greater automation and smart climate controls, refrigerants that are more friendly to the environment, and more developments with geothermal energy use. The only thing that will remain the same is the need for homes to be kept nice and comfortable all year round.
