For simple type, on server side:

public void Post([FromBody]string name)
{
}

on the client side, you just define if you want to send in json format:

    var dataJSON = "test";

    $('#testPostMethod').bind("click", GeneralPost);
    function GeneralPost() {
        $.ajax({
            type: 'POST',
            url: '/api/NewRecipe',
            data: JSON.stringify(dataJSON),
            contentType: 'application/json; charset=utf-8',
            dataType: 'json'
        });
    }

If you want to make it work in complex type, from server side you should define:

public class RecipeInformation
{
    public string name { get; set; }
}

public class ValuesController : ApiController
{
    public void Post(RecipeInformation information)
    {
    }
}

And from client side:

    var dataJSON = { name: "test" };

    $('#testPostMethod').bind("click", GeneralPost);
    function GeneralPost() {
        $.ajax({
            type: 'POST',
            url: '/api/NewRecipe',
            data: JSON.stringify(dataJSON),
            contentType: 'application/json; charset=utf-8',
            dataType: 'json'
        });
    }
