Brief rant, brief recipe

Ok, ok, you’ll get a recipe in a minute. First, a brief rant:

This is a common misunderstanding: a frame with a “stiff” (meaning, doesn’t move side to side much when you’re sprinting up a hill) bottom bracket is faster/more efficient/better for racing.

This is a bunch of crap, as anyone who has taken high school physics can tell you. 
-To make your bb move side to side, there has to be a force applied that makes it move that way.
-You generate this force when you pedal, because you’re not a robot and you can’t generate all your power in exactly the direction it needs to go to move the pedals. If you could somehow generate no side to side forces while pedaling, you wouldn’t see the BB move side to side no matter how flimsy your frame was.
-If you have a very stiff frame, the bb will not deflect to the side as much, but that does not mean that any extra energy goes into propelling the bike forward. The force still goes into flexing the frame/bb sideways – it’s just that since the frame is stiffer, it resists that force better. The end result in terms of watts to the ground is the same regardless of BB flex. 

Put another way: you cannot make your bike go by pushing sideways on the bottom bracket – it won’t work if the BB hardly moves, and it won’t work if the BB moves a lot.

That’s not to say that super flexy is a good thing, but if you are buying a stiff bike because you think it’s somehow going to make you faster/more efficient, you are throwing your money away. 

Now! Recipe:

Waltworks Peanut Satay

Put all of these in a pot:
-1 can coconut milk (NOT light!)
-1/4c red or green Mae Ploy curry paste (cut back on this for the milquetoast relatives from Iowa)
-1/2c peanut butter (sugary skippy type)
-1/4c sugar (you can get away with none if you want – taste test first and see if you want to add any)
-1/2 tsp salt
-2 tbsp white vinegar

Bring it all to a boil, simmer for a minute or two, and you’ve got some kickass peanut sauce for dipper or pouring directly into your gullet.
