00:00:00,520 --> 00:00:03,600
Speaker 1: Welcome to brain Stuff from house stuff works dot com

2
00:00:03,600 --> 00:00:14,520
Speaker 1: where smart happens. H I am Marshall Brain with today's question,

3
00:00:15,000 --> 00:00:19,000
Speaker 1: what are hot dogs made from? Hot Dogs, also called

4
00:00:19,120 --> 00:00:24,080
Speaker 1: Frankfurter's were first created in Frankfurt, Germany, in eighteen fifty two.

5
00:00:24,560 --> 00:00:27,440
Speaker 1: At its heart, a hot dog is just a sausage.

6
00:00:27,880 --> 00:00:30,680
Speaker 1: Hot Dogs are now made by hundreds of companies all

7
00:00:30,720 --> 00:00:34,320
Speaker 1: across the globe, and each company has its own secret recipe.

8
00:00:34,640 --> 00:00:39,479
Speaker 1: In general, however, hot dogs contain meat, meat, fat, a

9
00:00:39,720 --> 00:00:43,720
Speaker 1: cereal filler for example, bread crumbs or oatmeal or flour,

10
00:00:44,120 --> 00:00:47,599
Speaker 1: a little egg white, and some spices. My mother has

11
00:00:47,640 --> 00:00:50,840
Speaker 1: a recipe that contains one point five pounds of pork,

12
00:00:51,240 --> 00:00:54,240
Speaker 1: three quarters of a pound of pork fat, a quarter

13
00:00:54,360 --> 00:00:58,680
Speaker 1: cup of bread crumbs, an egg white, a little water, salt, pepper, onion,

14
00:00:58,680 --> 00:01:02,240
Speaker 1: and garlic to taste. Note that this recipe leaves out

15
00:01:02,280 --> 00:01:05,920
Speaker 1: the preservatives, coloring, and the sodium nitrate that you would

16
00:01:05,920 --> 00:01:09,360
Speaker 1: find in store bought hot dogs. Many brands leave out

17
00:01:09,400 --> 00:01:13,119
Speaker 1: the breadcrumbs and say no cereal fillers on the label.

18
00:01:13,640 --> 00:01:17,120
Speaker 1: Cereal fillers got a bad name because some manufacturers got

19
00:01:17,160 --> 00:01:21,640
Speaker 1: greedy and started using more filler than meat. These ingredients

20
00:01:21,680 --> 00:01:25,040
Speaker 1: are blended together in a meat grinder or a food processor,

21
00:01:25,160 --> 00:01:28,920
Speaker 1: and then they're stuffed into natural sausage casings. Once the

22
00:01:28,920 --> 00:01:31,440
Speaker 1: hot dogs are stuffed, you can pre cook them. You

23
00:01:31,480 --> 00:01:34,119
Speaker 1: can boil them in water for fifteen minutes and then

24
00:01:34,200 --> 00:01:37,680
Speaker 1: refrigerate them or freeze them. All hot dogs bought at

25
00:01:37,720 --> 00:01:40,480
Speaker 1: the store are pre cooked like this. When you're ready

26
00:01:40,520 --> 00:01:44,560
Speaker 1: to eat one, you cook it again by boiling, microwaving, frying,

27
00:01:44,680 --> 00:01:48,760
Speaker 1: or grilling it. Be sure to check out our new
