Can't Find Yeast? Grow Your Own at Home With a Sourdough Starter

Baking bread can relieve stress and it requires long stretches of time at home that many of us now have. But shoppers have been panic-buying some surprising items since the start of the COVID-19 crisis. In addition to pantry staples like rice and beans, yeast packets are suddenly hard to find in grocery stores. If you got the idea to make homemade bread at the same time as everyone on your Instagram feed, don't let the yeast shortage stop you. As long as you have flour, water, and time, you can grow your own yeast at home.

While many bread recipes call for either instant yeast or dry active yeast, sourdough bread can be made with ingredients you hopefully already have on hand. The key to sourdough's unique, tangy taste lies in its "wild" yeast. Yeast is a single-celled type of fungus that's abundant in nature—it's so abundant, it's floating around your home right now.

To cultivate wild yeast, you need to make a sourdough starter. This can be done by combining one cup of flour (like whole grain, all-purpose, or a mixture of the two) with a half cup of cool water in a bowl made of nonreactive material (such as glass, stainless steel, or food-grade plastic). Cover it with plastic wrap or a clean towel and let it sit in a fairly warm place (70°F to 75°F) for 24 hours.

Your starter must be fed with one cup of flour and a half cup of water every day for five days before it can be used in baking. Sourdough starter is a living thing, so you should notice it start to bubble and grow in size over time (it also makes a great low-maintenance pet if you're looking for company in quarantine). On the fifth day, you can use your starter to make dough for sourdough bread. Here's a recipe from King Arthur Flour that only calls for starter, flour, salt, and water.

If you just want to get the urge to bake out of your system, you can toss your starter once you're done with it. If you plan on making sourdough again, you can use the same starter indefinitely. Starters have been known to live in people's kitchens for decades. But to avoid using up all your flour, you can store yours in the fridge after the first five days and reduce feedings to once a week.

The Reason McDonald’s Doesn’t Sell McRib Sandwiches Year-Round

McDonald's McRib sandwich is officially back. Some people think the McRib is a 70-ingredient abomination, while others can't get enough of the barbecue pork sandwich. Whether you love it or hate it, the divisive dish always generates buzz whenever it comes back to menus after a periodic hiatus. According to CNN, the novelty surrounding the McRib isn't just a plus that comes with its seasonal status—it's the driving force behind its appeal.

McDonald's has built an empire around serving comforting, familiar foods that are consistent across thousands of locations. That business model doesn't apply to the McRib. Customers can't just walk into their local McDonald's restaurant any time of year and expect to find one: They have to follow the news and/or use online McRib trackers to keep tabs on the elusive sandwich.

Though the McRib has a devoted fan base, it will likely never secure a permanent spot on the McDonald's menu. That's because fast food companies know that having at least one seasonal item is good for business. When diners know that something is only around for a limited window, they're more motivated to make time to buy it than they would be if it was always there waiting for them. Temporary dishes can also add variety to a menu that's relied on the same staples for decades.

It took a long time for the McRib to grow into a cult sensation. When it first appeared in McDonald's stores in 1981, sales were underwhelming, and it was taken off menus in 1985. When it resurfaced in 1994, it had nostalgia and novelty on its side, and people were more willing to give the rib-shaped mystery meat a chance. By 2005, it was popular enough to become a recurring menu item.

The sandwich will return to select U.S. McDonald's restaurants nationwide on Wednesday, December 2, 2020, ringing in the start of McRib season. But as fans know too well, the item won't be around for long, so pop an antacid tablet and pick one up while you still can.
