Step son asked me to teach him to cook

So random step son post, my 17 year old step son (Who I am now adopting!) Said to me 20 minutes ago "Mom, can you teach me how to cook?" His reasoning is he feels like it will be a nice hobby to help him stay sober and then he can teach his little brother to cook in case we die (okay😐). But we are gonna make pancakes tomorrow. My husband is a little jealous that he's gotten closer to me than him. Actually side story

Anyone who read the post about me and my step son having a heart to heart and he hugged me for the first time, when I told my husband he said "Seriously?! Maybe I can get one. Hey son want a hug?!" And my step son gave him the biggest wtf look and said "No..." Lmao.

Edit: They actually do have a relationship now and gave bonded. He's just closer to me.
