Add some new tools to your culinary skill set with some virtual help from chef-owner Erin Miller and her Urban Hearth crew. The Cambridge eatery will be offering a handful of online classes in January and February so you can bone up on basics like spice blending, knife skills and fish cookery or perfect the art of biscuit making. The tutorials range in price and some are in the evening hours while others are scheduled for weekend mornings, which is all to say, you’ll be able to find a little something that suits you (or possibly a giftee that you may have overlooked). Peruse the options online here and keep checking back for additional info and more classes.
