Conditional random selection

So i have a JSON file that is populated with recipes, a sample from the file:

{
      "id": 6,
      "name": "Lobster roll",
      "type": "fish",
      "ingredients":[
        {"item": "Lobster","amount": 0.5},
        {"item": "Baguette","amount": 8},
        {"item": "Garlic","amount": 2}
      ]
},
{
      "id": 7,
      "name": "Potato and leaks soup",
      "type": "vegetarian",
      "ingredients":[
        {"item": "Water","amount": 0.5},
        {"item": "Potato","amount": 8},
        {"item": "Onion","amount": 2}
      ]
}

What i want to achieve is to select random recipes from the JSON-file, for example 7 recipes. But with the condition that at least 25% of them should be of the type: fish. As every recipe is tagged with what type it is in the JSON-file.

I am using the random.sample() function, so how do i get the condition in play here?

import json
import random

with open('recipes.json') as json_file:
    data = json.load(json_file)

random = random.sample(data, 7)

for i in range(0, len(random)):
    print(random[i]["name"])
