Move insertion with unordered_map having multiple values

I tried the below code for move and initializer list insertions. The later works but not the move insertion. Can someone help me with the right solution here ?

#include <iostream>
#include <iostream>
#include <string>
#include <unordered_map>
using namespace std;


int main ()
{
  std::unordered_map<std::string,std::pair<double, double>>
              myrecipe;

  myrecipe.insert (std::make_pair<std::string,std::make_pair<double,double>>("eggs",(1.0,6.0)));
  myrecipe.insert ( ,{"salt",{0.1, 2.0}}} );   

  std::cout << "myrecipe contains:" << std::endl;
  for (auto& x: myrecipe)
    std::cout << x.first << ": " << x.second.first << ":" << x.second.second << std::endl;

  std::cout << std::endl;
  return 0;
}
