The pandemic has brought a proliferation of new virtual cooking classes. #AskChefsAnything was an early entry, auctioning off interactive sessions to benefit immigrant workers, among others. Now there is Delicious Experiences, from a company based in Israel. It connects viewers with food experts for personalized one-on-one classes. Learn about burgers from Nate Appleman, about wine from Thomas Pastuszak, about brunch from Elizabeth Blau and about spices from Lior Lev Sercarz, and more. YesChef, another start-up also originating in Israel, counts names like Nancy Silverton, Francis Mallmann and Sean Brock on its roster. Instruction involves about five hours of video content, including documentary footage about each expert and about dozen lessons, ranging from 10 to 50 minutes, which do not have to be viewed all at once.
