What skills would you recommend for a medium-level culinary position?
Is there any particular skill set I should spend more time and energy on acquiring and practicing?
You should have some knowledge of baking and be confident in being able to execute simple baking tasks like biscuits, scones, cookies, muffins, foccacia, yeast rolls, etc. Get to know how every piece of equipment in any kitchen works, even if you don't use it in your position. Chances are someday you will somewhere else. If you are line cooking, be at least familiar with the other positions on the line besides yours. Being proficient and competent across a wide variety of positions and situations will make you more valuable and also a stronger cook. Don't be afraid of stepping out of your comfort zone and doing things you have not done before.
