Default WordPress comment system may look boring but after using few of these stuff like Disqus and other comment systems for 4 out of 7 year's of my site's age, default system is the best. This way it stays in-house- comment, commenter's privacy, etc. Maybe if there was a huge network of commenters, that would be different. But till then, I would stick to the default system. Maybe the other idea is probably to use GIFs for instruction content like recipes. If you want to express or show something which is not easy to do with words and single/multiple images don't exactly do the job, GIFs are a good idea. Just get a tripod and record the particular action maybe not longer than 6-10 seconds, convert the video to GIFs through online converters (they are many of them and even some standalone software too) and embed that. I noticed that if I click your name in an article, it redirects to the main site. Since its a single author site, you could try linking it to your "About Sumit Malhotra" page. For an introduction page, maybe a full width would be nice, if your theme allows it. It looks cleaner, wider and usually people check such page out to know more about you rather than reading the content that you're specializing it. Its really a well-written self-introduction title that expresses what you do and how you connect with food and other business. Maybe a good front facing landscape shot of you as a feature image would be a better touch.
