7 Premium Demi-glace Hamburger Steak

7-Premium Gold Gold Open-flame Grilled Hamburger Steak

There are two types of demi-glace hamburgers sold in the chilled prepared foods section of 7-Eleven: the 7 Premium Demi-glace Hamburger for 213 yen and the 7 Premium Gold Kin no Naibiyaki Hamburger for 397 yen (prices include tax). The gold one is almost twice as expensive, but how different is the taste? We were curious, so we compared them!

Difference in Warming Time

The recommended cooking time for the demi-glace hamburger steak is 1 minute and 40 seconds in the microwave and 5 minutes for boiling, whereas the recommended cooking time for the gold direct-heating hamburger steak is 3 minutes and 20 seconds in the microwave and 10 minutes for boiling. The cooking time is about twice as long. If you are extremely hungry or too busy to spare even a second, we recommend the demi-glace hamburger steak, which can be cooked in a shorter time.

This time, I will try it boiled.

The golden hamburger is slightly bigger.

Comparing the size of the hamburger steaks on a plate, the golden hamburger steak is larger. The weight of the demi-glace hamburger weighs 100 grams, while the gold hamburger weighs 200 grams, which is twice as much. At this point, I feel that the reason for the doubled price has been recovered, but I will continue the comparison.


The demi-glace hamburger steak is about 8 x 6.5 cm in maximum diameter and about 2 cm thick. On the other hand, the golden direct-fired hamburger steak is about 9 x 7 cm in maximum diameter and about 3 cm thick.

The demi-glace sauce also seems to be thicker in the golden hamburger steak.

Difference in taste and texture of hamburger steak

Demi-glace hamburgers are soft and fluffy! When you put it in your mouth, it melts away softly without you having to put much effort into chewing it. Beef and pork are used as ingredients, and there is no meatiness at all, making it refreshing and delicious.



On the other hand, the golden open-flame hamburger steak is more resilient than the demi-glace hamburger steak. The hamburger steak is soft and fluffy when you bite into it, and has both a good meaty chewiness and a smooth texture. The meat used in this hamburger is only beef, and the more you bite into it, the more umami you feel.

Difference of Demi-glace Sauce

Thick and rich demi-glace sauce that goes well with hamburgers. The demi-glace hamburger steak sauce has a good balance of richness, umami, and a hint of sourness, and is easy to eat for both children and adults.


The demi-glace sauce of the Kin no Naibu Yaki Hamburger steak has less acidity than that of the demi-glace hamburger steak, and has a rich, deep, and profound flavor. The moment I ate it, I said, "Yum! You can eat a cup of white rice with this sauce alone.

Comparison summary: Which one should you buy?

Demi-glace hamburger steak: Light and easy to eat
Golden Open-flame Grilled Hamburger Steak: Rich and thick taste

Overall evaluation of size and flavor, the demi-glace hamburger steak is just right for a side dish for lunch or a light lunch. It would also be good as a hamburger steak sandwich between bread. On the other hand, the golden direct flame-grilled hamburger steak has a volume and filling that is comparable to a main dish for dinner. The hamburger steak and sauce tasted authentic, and I felt that this was a delicious dish that was well worth the price.

So, I personally would like to recommend the golden direct-fired hamburger steak. To be honest, at just under 400 yen a piece, it is quite expensive... but if you only eat it once in a while, it's totally worth it! Making your own demi-glace sauce is a hassle, and if you think about eating out, it's cheap, tasty, and a good value!


Speaking of the "direct flame-grilled" hamburger steak, I didn't have the impression that the hamburger steak was very well browned or that it had a particularly strong aroma, but I thought the demi-glace sauce was rich and delicious. It is up to you to decide what you think of the "direct flame-grill".
