History of Oseng Mercon

Oseng mercon is known nationally for its intense heat. Imagine a party in your mouth with beef and red bird-eye chilies doing the salsa! In Javanese, “mercon” means firecracker, and “oseng-oseng” is all about stir-frying with chili peppers. So when you dive into this dish, get ready for a fantastic explosion of flavors that’ll have your taste buds dancing!

The history of this food was there’s this awesome lady, Bu Narti, from Yogyakarta, Indonesia. Back in the late 90s, things were kinda rough in Indonesia due to the financial crisis, and Bu Narti faced her own personal struggle when her husband passed away. Moreover, during an Islamic Feast (idul adha), Bu Narti’s family ended up with loads of meat – cow meat, skin, feet, and fat, you name it.

To make a living, she decided to start a simple street food stall. Now, here’s the twist: she came up with this meat dish loaded with a ton of chili peppers. And let me tell you, this dish was so fiery, it was like a party of firecrackers (which, in Javanese, is “mercon”) going off in your mouth. That’s how it got its catchy name!

When she first opened her stall on Jalan KHA Dahlan in ’97, Oseng-oseng mercon was the star of the show, making people crazy for that spicy kick. And guess what? The love for this dish spread like wildfire to other cities too. Luckily, it gets even better! The original Mercon stall is still kicking today, and this oseng mercon has become a must-try in Yogyakarta.

So, next time you’re in Yogyakarta, you absolutely have to try this spiciness extravaganza. It’s like a fireworks show for your taste buds!

Craving for Savory and Spicy Food

I have a ridiculous story behind making this recipe, recently due to my PMS, I got plenty of cravings for spicy, oily food. my mind was mouthwatering with chilis, let me tell you, I’m not really into a very spicy food lover, I’m just an average to mild spicy lover lol. So it’s kinda unusual for me.

Then, for the following days after I just figured out that I was getting menstruation, I search for the reason behind my craving, even though The connection between craving spicy food and PMS (Premenstrual Syndrome) or menstruation isn’t fully understood and may vary from person to person. However, Here are some theories from the internet that could explain this phenomenon:

  1. Hormonal Changes: During the menstrual cycle, hormone levels fluctuate, particularly estrogen and progesterone.
  2. Endorphin Release: Spicy foods can trigger the release of endorphins, which are natural “feel-good” chemicals in the brain.
  3. Nutritional Needs: Some experts suggest that the body’s nutritional needs can change during menstruation.
  4. Cultural and Psychological Factors: Cravings are influenced by various factors, including cultural background and personal experiences.

I’m grateful that I finally discover this recipe, this is so yummy, spicy, and addictive, it can be your stress-relief food tho ( be careful with the aftermath) always be responsible and be sure of your body’s capability thru spicy food intake. Do not worry, you can always adjust the recipe measurement based on your preference😉

  • Onion; adds a sweet and savory flavor to the dish, enhancing the overall taste and aroma.

  • Red and Green Curly Chili; add heat and a vibrant red and green color to the dish. They contribute to the milder spiciness and flavor complexity and visual appeal
  • Cayenne Pepper/Redbird eyes chili; I use redbird eyes chili adds a strong kick of spiciness to the dish. Adjust the amount according to your desired level of heat. This is what makes firecracker beef super spicy
  • Lime Leaves sliced; provide a citrusy and aromatic flavor to the dish.
  • Galangal; A rhizome similar to ginger, galangal adds a distinctive earthy and citrusy flavor to the dish.
