No sugar, no nothing else in the pot when you juice. That can be added later. You waste sugar that doesn't drop through into the juice (it stays with the pulp) and skew the results (because sugar does melt). The object is to end up with the pure juice have the most possible uses.

I read a review of some of the OTC rapid COVID antigen tests (home variety) and found one that appears to be in stock at the neighborhood Walgreens. The review says that FlowFlex is the most reliable and comes just one test to a box, but that the FDA believes it is accurate enough that you don't need a second test a few days later to learn if the first test was accurate. Once is enough. $10 a pop now, but in the near future the federal government will make home tests available for free (or reimburse purchases). You'd think by now we'd have figured out all of the COVID stuff going on, but if you read America Is Not Ready for Omicron in The Atlantic, you got an eyeful of news about the most recent variant:

The coronavirus is a microscopic ball studded with specially shaped spikes that it uses to recognize and infect our cells. Antibodies can thwart such infections by glomming onto the spikes, like gum messing up a key. But Omicron has a crucial advantage: 30-plus mutations that change the shape of its spike and disable many antibodies that would have stuck to other variants. One early study suggests that antibodies in vaccinated people are about 40 times worse at neutralizing Omicron than the original virus, and the experts I talked with expect that, as more data arrive, that number will stay in the same range. The implications of that decline are still uncertain, but three simple principles should likely hold.

First, the bad news: In terms of catching the virus, everyone should assume that they are less protected than they were two months ago. As a crude shorthand, assume that Omicron negates one previous immunizing event—either an infection or a vaccine dose. Someone who considered themselves fully vaccinated in September would be just partially vaccinated now (and the official definition may change imminently). But someone who’s been boosted has the same ballpark level of protection against Omicron infection as a vaccinated-but-unboosted person did against Delta. The extra dose not only raises a recipient’s level of antibodies but also broadens their range, giving them better odds of recognizing the shape of even Omicron’s altered spike. In a small British study, a booster effectively doubled the level of protection that two Pfizer doses provided against Omicron infection.

Second, some worse news: Boosting isn’t a foolproof shield against Omicron. In South Africa, the variant managed to infect a cluster of seven people who were all boosted. And according to a CDC report, boosted Americans made up a third of the first known Omicron cases in the U.S. “People who thought that they wouldn’t have to worry about infection this winter if they had their booster do still have to worry about infection with Omicron,” Trevor Bedford, a virologist at Fred Hutchinson Cancer Research Center, told me. “I’ve been going to restaurants and movies, and now with Omicron, that will change.”

Third, some better news: Even if Omicron has an easier time infecting vaccinated individuals, it should still have more trouble causing severe disease. The vaccines were always intended to disconnect infection from dangerous illness, turning a life-threatening event into something closer to a cold. Whether they’ll fulfill that promise for Omicron is a major uncertainty, but we can reasonably expect that they will. The variant might sneak past the initial antibody blockade, but slower-acting branches of the immune system (such as T cells) should eventually mobilize to clear it before it wreaks too much havoc.
