Hobbies

Me & Cooking

Let me introduce my cooking philosophy throught a few key points

  • Passionate Home Cooking: I cook often at home, driven by a deep passion for creating incredible food.
  • Relaxed Approach: I don't sweat the small stuff. I'm all about enjoying the process and flavors, not stressing over perfection.
  • Feeding Loved Ones: I love cooking for my family and friends, and I believe there's nothing quite like a homemade meal to show you care.
  • Budget-Friendly Goodness: I'll show you how to make delicious meals that won't break the bank.

Inspiration

I drew my inspiration and passion from a multitude of talented YouTubers. Here's a curated list of some of the best who have played a significant role in shaping my culinary journey:

Plants & Gardening

I've always had a deep appreciation for nature, growing up in the countryside helps a lot. However, my passion for plants truly blossomed during a high school biology class when I witnessed chloroplasts moving under a microscope. Those tiny green organelles, brimming with life and releasing oxygen bubbles, captivated me.

My journey into the world of plants began in my high school years, largely influenced by YouTube. Over time, my interests expanded to gardening, agriculture, and eventually led me to explore "self-sufficiency" YouTubers. These individuals are dedicated to achieving energy and food self-sufficiency (without delving into extreme survivalism). It all intertwined with my fascination for culinary pursuits like making jams and preserving food.

My passion for music, particularly electronic music, ignited during my middle school years when I stumbled upon YouTube channels like MrSuicideSheep and Monstercat. From that moment on, I never stopped listening. I take pride in exploring the entire spectrum of electronic music.

If you're curious about what's currently playing in my world, I invite you to check out my Last.fm profile, which aggregates my Soundcloud listens and gives you a glimpse into my musical journey.
